This is a late reply, but from my experience a really good removal station is one made by a company called CCRCo. They make a micro-abrasive station that addresses all the ESD concerns. They utilize a reusable media that is really cost effective. The

BGA failure after coating

We doubt that Humiseal 1A33 is causing opens in your assemblies. We'd guess the opens occur earlier in the process, but are not hard failures. So, you pass your tests. When applied, the conformal coat flows into the gap in the ball crack and insulate

Solder on gold finger

We had a similar problem with gold contact pads. Cleanliness is paramount. If you are using foil tensioning system, wash the foil in a stencil wash before use as the cardboard cassettes may be contaminated. Be very careful when loading into a frame f

Corrosion due to RTV adhesive

Hey that was me way back! Anyways, use Dow 3140 (self leveling) or Dow 3145 (peanut butter consistency) and call it a day. No out gassing/acidic properties. 3140 also contains a UV tracer for black light inspection. Any tall caps should be epoxied if

Urethane Coating (1A33)

Silicone contamination could appear as fisheyes or dark spots under UV light. 1A33 can be heat cured but is a single component oxygen cure coating - it needs a source of oxygen to cure. An unvented oven may slow or limit the cure. Check out the TDS

Conformal Coating Coverage

The easy part is to determine which parts should be coated. The harder part is making sure the parts that should not be coated do not get coated. I don't even want to think about the amount of labor and materials I've lost due to conformal coat get

Conformal coating removal machine

We bought a conformal coating removal machine AKA a sand blaster at an auction. It is a CCR2000 especially made to be ESD safe. Does anyone have any experience with sandblasting conformal coating? We mostly use humiseal 1A33 and UV40. When we use the

Dymax vs Humiseal Urethane Confomals.... Anyone?

Good morning Jamie. I work at a CM and can offer some input on process flexability. I do not have any data on how reliable the coating is but I can say that they are both very difficult to control. Will you be selective coating or full coating? Ho
