GT 8 years ago every board saw "touchup". Touch was done to fix boards to conform to A-610. Now A-610 allows less than complete hole fill. Our operators were totally freaking nuts about touching boards. They touched each others touch and on and o

A flexible array support system is superior in the following categories discussed in the 'tooling classes' thread. -High Flexibility -Effective on a variety of products -Low operator intervention -Conforms to PCB, so it is both accurate and repeatab

Todd, All liquid coatings are Newtonian - they follow gravity so they do indeed run away from sharp leads and edges. Silicones are generally worse because they have very low surface energy - although this is an asset when trying to get under compone

Obviously, clean enough :-) I don't think I've ever seen a specification, although some companies obviously have in-house ones. It would depend on the process used. For ex., if you used Parylene, where the coating is done in a vacuum chamber, you wou

On circuit board assemblies first pass yields need to be above 98%, if a supplier is below this level it is a indication that: he has poor control of the manufacturing process; Poor component selection (price over quality; excepted a poor design from

| Has any one seen failures of chip resistors after 1-2 years where the junction between the silver termination and the restive element on the top of the ceramic has corroded through. This results in a high resistance failure after this period of tim

| We appear to receive certain standard discrete components (1206,0805,&0603)that deviate in size and shape to the extent that vision processing discard rates are through the roof. Does anyone else have problems with vendors being unable to produce
