![]() ![]() ![]() ![]() For wave soldering, the flux is typically sprayed onto the circuit board before it passes over the molten wave of solder. Rosin flux can be used for automated PCB assembly depending on the needs of the circuit board. Now let’s examine how rosin flux is used during the soldering process. In addition to the rosin and the activators, the flux will also contain other solvents and additives to assist with the soldering and protect the metal against corrosion. RA (rosin activated): This rosin flux contains the highest levels of activators for cleaning, and it will also leave the most residue after soldering.This flux will leave some residue that is normally not an issue. RMA (rosin mildly activated): This category contains a higher level of activators sufficient for cleaning PCB pads and holes, as well as the component pins, during soldering.Due to its low level of activity, this rosin flux will not produce any harmful residue during soldering. R (rosin): This is the mildest form of rosin flux, which contains the least amount of activators and is only intended for clean metal surfaces.The level of activity of these acids is further separated into three categories of rosin flux: It also contains different kinds of acids as activators, which promote the wetting of the molten solder by removing oxides from the metal. Rosin flux’s base material is composed primarily of rosin extracted from the sap of pine trees. No-clean flux doesn’t require cleaning due to its low level of activity, but as a result, it is also not as effective in preparing the surfaces for soldering. This is very effective for preparing the surfaces for soldering but requires thorough cleaning and inspection soon afterward to guard against flux contamination or board damage if not removed in a timely fashion. The water-soluble fluxes made from organic materials other than rosin are extremely active during soldering. The flux also helps promote the wetting of the solder, which establishes how well the molten solder will flow onto the surfaces being joined.įluxes for soldering electronics are separated into three categories: Rosin, Water Soluble (or Organic Acid), and No-Clean. To help with the soldering process, flux is used to chemically clean the metal surfaces by removing the oxides as well as any other impurities. In the case of electronics, these oxides can impede the formation of a good solder joint during circuit board assembly. When metal is exposed to air, oxides can form on unprotected surfaces. There’s more to tell concerning this secret ingredient let’s explore the use of rosin flux in PCB assembly. Different types of flux are distinguished by the base materials used to create it, with rosin being one of the more common variants used in circuit board assembly. Flux facilitates this soldering process by cleaning the metal surfaces before they are fused. Solder is a combination of metal alloys that, after melting, fuses the pin of a component to a metal pad or hole on a circuit board to create an electrically conductive connection. Working together with the solder is a substance that many aren’t aware of called flux, but without it, we wouldn’t be able to reliably solder a single part. They aren’t the only ones to rely on a secret, though soldering electronic components to a circuit board relies on a hidden ingredient, as well. ![]() Many popular foods and restaurant chains raise interest in their products by advertising a “secret” ingredient. ![]()

![]() ![]() Rigged with a matching slow pitch rod, it would make a perfect tool to practice the latest “snap jigging” techniques for mid-depth pursuit of coastal gamefish. This translates to 11.25 pounds of drag at strike and 17 pounds of stopping power at full, which is plenty when you consider that this diminutive reel is designed to hold either 440 yards of 20-pound or 350 yards of 30-pound superbraid. The quadrant’s generous adjustment range allows for a gradual ramping up of drag power, which includes a “Strike” indent about two-thirds of the way to the “Full” setting. The drag is silky smooth with a click lever that stays in place. Other high-end components on the Rage reels include a dual drag design, nine stainless steel bearings, a drop gear box and a removable reel foot for easy cleaning or replacement. A cold-forged aluminum sideplate on the crank handle side of the Rage, along with tempered stainless steel gears, add to its overall bullet-proof design. Maxel accomplishes this shedding of unnecessary weight by starting off with a billet of aluminum that is CNC machined with various spaces, gaps and geometric holes in its frame and side to save a few precious ounces, but not sacrifice the metal’s inherent stiffness and strength. At only 14 ounces, it’s easy to hold in your hands all day long with a minimum of fatigue. Right from the get-go, even an untrained eye will realize that this is no ordinary downsized jigging reel, but a high-end piece of well-constructed machinery. My sample featured a black body with a gold spool and trim, and had striking good looks. I requested the micro-sized 25H model in whatever color was available from their kaleidoscope of options and it showed up a few weeks ago. Its predecessors had brought a lot of stripers, deepwater sea bass and tog, summer flounder, cod, pollock and football tuna to boatside for me and my charter customers and I was well aware of the positives and the occasional negatives of the Maxel product line. I currently use the Hybrid star drag and the Ocean Max lever drag reels, so I was anxious to get my hands on a sample of the newest Rage to see how it measured up to its siblings. The Rage jigging reel models represent the top of the line for Maxel. The heavier Maxel Rage 60H, 90N and 90 are meant to handle larger near offshore and deepwater gamefish, but are still relatively light weight with run-stopping drag capability. The smaller 25H right and left hand models are a huge hit with the “slow pitch” jigging crowd looking for a powerful micro-sized outfit. These reels grabbed a lot of attention for their smooth gears and drags, combined with a tough as nails construction and do-it-all attitude. Introduced last summer at the 2018 ICAST tackle show, Bimini Bay Outfitters made a big splash with the USA debut of their proven high-end Maxel Rage lever drag reels. ![]() They specialize in manufacturing quality reels for big game trolling and deep water jigging fishermen who take their sport very seriously and insist on the finest quality at reasonable costs. Their experience as sub-contractors producing aluminum parts for some of the biggest names in the fishing business has honed their manufacturing skills and expertise. ![]() Just in case you didn’t know, Maxel Fishing Tackle has been manufacturing high quality big game trolling and deep water jigging reels since 2003. ![]() ![]() ![]() In 2012, the Governor of Michigan and Michigan Legislature passed legislation requiring the Michigan Virtual University to establish a center for online learning research and innovation, known as the Michigan Virtual Learning Research Institute.Īfter redefining its mission and vision in 2004, MVU now serves the K-12 education community exclusively through the Michigan Virtual School, Michigan LearnPort and Michigan Virtual Learning Research Institute.

The tricep might function as one intrinsic system, but it is in reality made up of three different parts, namely the medial, lateral, and long heads.Īll three heads work as a group, but they also perform independent functions. The tricep or triceps brachii is the muscle that makes up the flesh part on the back of your upper arm. The cable pullover also works the triceps of your arm, specifically the long head. This not only provides a broader back that will improve your physique but also enhance your performance in functional and sports activities. Using the lats to pull the cables helps you isolate and activate them to increase their strength and muscle mass. In simpler terms, the lat muscle is essential for the proper functioning of the body. Other than this, the lat works as a stabilizer for the torso and a necessary respiratory muscle. It allows the scapular rotation to rotate, adduct, or extend the arm. The lats help motion take place in the shoulder joint. ![]() The widest of all muscles in the human body, the latissimus dorsi, works together with other connecting muscles to control the scapular movement of the shoulder blade. It is a thin, superficial muscle covering most of the other back muscles except the traps. The latissimus dorsi muscle is a broad, flat muscle that spans the entire length of the middle and lower back. In a nutshell, the cable pullover is an upper-body strengthening exercise. However, since no exercise is a hundred percent isolated, other muscles like the triceps, pectorals, teres major, rhomboids, and deltoid all contribute to your arm movement during the exercise. The primary muscle worked during the cable pullover is the lats of the back. Regardless of the variation, the method is the same: the movements only occur in the shoulder joint. While there are other variations of the cable pullover, this is the way to perform the conventional cable pullover. ![]() When performing the cable pullover, you face the cable machine, grab the overhead pulley, and pull the cable towards your thighs with your lats. The steel machine offers machine-assisted support when you perform the exercise, taking away the need for a constant awareness of your form, which would be the case in free weight pullover variations. ![]() Although it targets the back, a cable pullover uses the action of shoulder extension to move the shoulders to reach the target muscle.Ī cable pullover is a simple exercise performed using a cable machine, a steel structure containing weights attached to retractable cables. If better upper body muscle definition and more significant muscle mass happen to be on your wishlist, then you may want to consider adding this to your weekly training schedule.Įverything You Need To Know About Cable PulloversĪ cable pullover is an isolation exercise that primarily targets the latissimus dorsi muscle, also known as the lats, of the back. It is an isolation exercise designed to activate the major muscle groups in your upper body. From the cable bicep curl to the standing cable row, you can never run out of the possible exercises you can do with a can't machine.Ī cable pullover is one of the numerous practical exercises that can be performed using a cable machine. During the lowered aspect (when the bar is at the abdomen) the abdominal muscles can be squeezed to increase the intensity, and, consequently, get the most out of the exercise.One thing is for sure: the cable machine offers a plethora of exercises. The expansion occurs during the stretch at the starting position (when the arms are grasping the bar overhead). Machine pullovers, like its brethren pullover exercises, does allow for thorax (rib cage) expansion. Whereas with machine pullovers, the resistance remains relatively constant throughout the movement, even when the weight is over-face-which is essentially a resting aspect of dumbbell and barbell pullovers. With dumbbell and barbell pullovers, when in the lowered position (where the arms are parallel to the floor) there is great resistance, but when the weight is over-face (the starting position) there isn't a great deal of resistance. They are safer and easier to execute due to the fixed, semi-circular arc that the machine is set to travel through. Though not quite as effective in targeting the serratus muscles as dumbbell and barbell pullovers, they are considerably easier to execute, still effective, and safer. Machine pullovers are similar to dumbbell and barbell pullovers. ![]() ![]() ![]() Now, go to the Games page and scroll all the way down to the free area.

She likes to pour a little into a tin jar (it comes with the cleaner when you purchase through Sephora, or you can use your own), dip the tip of her brush in, and lightly swirl it on a paper towel until it’s clear. “You only need the littlest bit,” says Rosado. It’s on the pricier end, so all of our artists recommend using just enough to get the brushes clean. Karol Rodriguez, an editorial makeup artist based in New York City, is also a fan: “99 percent of the time I use this product to clean my brushes because it is incredibly effective, super quick, and dries immediately.” Rosado also named this as her top pick. Makeup artist Kasey Spickard swears by Cinema Secrets, which he prefers to others like Parian Spirit, which, in his experience, can leave an oily residue that impacts makeup application. To help you pick which cleanser is best for you, we spoke to eight experts about the makeup brush cleaners they use to keep their tools in tip-top shape.Ī pro makeup artist favorite, five of our experts recommend this fast-drying, antimicrobial cleanser for quick cleaning and disinfecting. Quick dry time is important too, so many of their picks are liquid, which clean and dry brushes in just a few minutes, versus cake soaps which require lathering and saturating the brush. Cinema Secrets has the most requested makeup brush cleaner on the market, known for its rich blue color and vanilla scent. All of our experts agreed that a good makeup brush cleaner is one that cleans effectively without having to scrub or tug on the bristles to get the job done. While the makeup artists we spoke to clean their brushes almost daily (between clients, sets, and the like), if you’re only using your brushes on yourself, cleaning them once or twice a week is plenty, unless, says Rosado, you’ve used blue eyeshadow or pink blush (both of which are stubborn pigments). Well-cared-for brushes perform better - allowing product to sit on bristles can ruin the integrity of the brush, thus shortening its lifespan, and, needless to say, dirty brushes are also breeding grounds for germs and bacteria that can cause breakouts and infection. ![]() It’s an easy step to skip, but properly maintaining your makeup brushes can mean the difference between buying new brushes every year or two or keeping them for much, much longer - Isabel Rosado, an editorial makeup artist, says she has had some of hers for a decade.
