I have boards coated with Humiseal 1B73. At a late point mfg. site we need to remove a series of 0603 resistors for optioning purposes. I have been trying to determine the fastest, easiest way to re-coat the pads after removal. Drying time of the coa

We are experiencing poor wetting on various components placed on a PCB with En-Tek coating. Is anyone else experiencing simular problems ? We have the following questions: 1. How can the thickness of the En-tek coating be measured? 2. Is En-tek vol

Humiseal probably won't work as most of them are solvent based or require pretty high temp cures. MicroCoat technologies manufacturers UV cure epoxy conformal coating materials that have been used to coat just about anythin (except the green fog) Cal

Check out Precision Valve & Automation Latham, NY Phone: 518-782-3436 They make a relatively inexpensive system for applying material. You can choose spray or valve dispensing or both. The product is built simply and has been relatively easy to set

We have experienced poor adhesion of acrylic conformal coating to plastic bodied IC�s. The observed symptoms of this are a blistering or lifting of the coating at the surface of the component, although peel testing has revealed that this is not alwa

| Does anyone out there can let me know how to clean a Entek Coating Board if I have a misprint during solder paste printing? According to the guys at Enthone, squeegee most of the paste off, then use Kyzen Lonox (which only removes 3% of the coating

Dull / shiny, I�m not sure that�s a proper indicator. If �Liquid Tin� adds a thin coat of solderable material without converting the corrosion on the surface of the lead, the corrosion will [probably] continue to increase and potentially affecting t

There is two major BGA coating camps. * Camp #1: "We require the coating to be under low stand-off devices but with no filleting. So we apply a thinned dip coat first, and then top-off with a proper spray coat" * Camp #2: "We want no coating under th
