Epic Disposable Lab CoatMore and more customers are telling us that when it comes to disposable clothing as long as it performs well they don’t necessarily need the high-priced brand. That’s why we’ve expanded our selection of Epic disposable lab coats, isolation gowns, coveralls, shoe covers and bouffant caps.

Epic features two choices of materials. You can select their standard breathable polypropylene which comes in a variety of fabrics weights to meet your requirements. This economical fabric is a smart choice for any dirty environment with little exposure to liquid contamination.

Their three-layer SMS fabric is exceptionally comfortable, breathable, and cloth-like. The middle microporus layer acts as a filter to keep out small particles and also repels non-hazardous liquids.

Epic’s top-notch quality, large range of products and affordable pricing lets you outfit your entire department with confidence and stretch tight budget dollars even further.

How Does Heat Shrink Tubing Work?

Posted on by Andy in Technical Articles Leave a comment

Heat Shrink TubingIf you think about it, heat shrink tubing works in the opposite way that most would imagine. Many objects expand when heated and contract when cooled, so the term “heat shrink tubing” almost sounds like an oxymoron. However, the key to how heat shrink tubing works lies in how it is made.

When heat shrink tubing is created its original diameter is what you would typically think of as the “post-shrinking” size. To make the tubing have a larger diameter it is heated to near its melting point and then expanded, typically by inflating it with a gas. After the tube is expanded then it is rapidly cooled so it retains its new shape. This is what makes heat shrink tubing work, as when you heat the tubing up it becomes soft and contracts to its original size.

The dimensions for heat shrink tubing make a lot of sense when you look at the production process. Most heat shrink tubing talk about the “expanded inner diameter” which is logical when you realize that the tubing’s normal state is the post-shrinking size. The shrink ratio is also determined during the production process, as you can make the ratio go from 2:1 to 3:1 by expanding it more when it is made.

Types of Fluxes

Posted on by Andy in Technical Articles Leave a comment

Kester Solder FluxWhen soldering, you often need to use a flux to create proper joints. There are many types of flux, and they can be found in liquid, spray, or pen form, as well as inside solder wire itself. Below is a brief overview of a few types of fluxes. As always, if you have any questions on the application of a specific product, the manufacturer is the best place to go for up to date information.

No-Clean

No-clean fluxes are rather weak, and the residue that they leave behind will typically not harm your devices. This is why they are called no-clean; the residue it creates can be left on the board and it will not corrode your parts. If you are applying a conformal coating to your PCB then you will need to clean off the residue from no-clean fluxes so you can ensure even protection.

Mildly Activated Rosin

Mildly activated rosin fluxes are a bit stronger than no-clean, but also typically leave a non-corrosive and non-conductive residue. These fluxes vary from manufacturer to manufacturer, so be sure to read the directions before leaving the residue to sit on a sensitive component. Mildly activated rosin fluxes also have a high thermal stability, ensuring that preheating does not degrade its solubility.

Activated Rosin

Activated rosin fluxes are the next step up from the mildly activated rosins. The added power in the activated rosin can remove oxides that no-clean and mildly activated fluxes cannot. The residue left from activated rosins may be corrosive, so check out the data sheet or talk to the manufacturer to see if your particular flux needs to be cleaned off the board after soldering.

Inorganic Acid

Inorganic acid fluxes are also very strong, perfect to help solder difficult metals. This can be extremely helpful for heavily oxidized metals, or for materials that have a low solderability. Again, a corrosive residue is left behind, so a hot water or solvent rinse is required to protect your board.

Water Soluble

These fluxes are made to be easily washed off, especially during wave soldering processes. Water soluble fluxes are some of the strongest, and will definitely corrode your PCB if left on, so be sure to thoroughly clean off any residues left behind by this flux.
