I have a knack for asking those "set-up" questions of sales types during their presentations. It's so bad, I don't even have to pay for lunch to attend SMTA meetings. The "presenter" pays for Dave. YES!!! I've read the Richard S. Clouthier "SMT S

| We have some SMT components with gold plated leads. They're actually LCC led packages. A good solder alloy to use would be Indium / Lead to reduce tin dissolution into the gold and avoid the resultant brittle intermetallic compound. However, a reco

| Does anybody have any reliable alternatives to device bake out for plastic bodied components. We do not use a whole package at time and therefore have to oven bake the balance before we can use them. | I have come accross dry nitrogen storage cham

| Certain board designs require the unavoidable use of non-plated holes and slots. Presently, this requires a trip back to the drill house to open up the aforementioned holes, to remove the unwanted plating. In situations requiring non-plated holes a

Hello, I am looking for suggestions for cleaning pcb's after the routing (fabrication) process. Keep in mind that these pcb do not have components intalled on them yet. We have considered pre-drilling the routing plunge points, but cost and capacity

I assume you're looking at stencil fab equipment because you need 'faster turns' than you can get from available stencil suppliers. While you're assessing this, consider other alternatives, such as: * Dispensing paste. [A very funny SMTNetter, livin

Glue has different mechanical, thermal, and electrical properties than solder. That's why all these very nice no-lead people are furiously trying to gin-up some wacky solder alloy, rather than using glue. Among the papers in the SMTA Knowledge base
