We don't do this, but if we had to and lacking better advice, for all components I�d dry pack according to J-STD-033, store in a low temperature and humidity controlled environment [maybe using some semicon fab inert storage cabinets], review the eff

The two first level cuts at comparing placement machines are: * Placement rate * Range of component capabilities This boils-down approximately to machine price. Virtually, everyone's feeders are priced similarly. Go to "Circuits Assembly" magazine

Larry, If you are asking about how to package your component in tape and reel, I would contact the 3M company. There are many tape companies out there, but my company has been very happy with 3M. If they don't have a tape that's stock, they'll guide

We send parts out to be tape & reeled. We do not send all loose parts out to be tape & reeled. As you would expect, we base our decision on: * T&R service company lead time * Our production schedule * Cost benefit of T&R versus some other productio

We are doing a field study to test the placement accuracy and calculate cpk of some machines in our plant. From previous readings, it is suggested that you buy glass board kits from Accuspec, Topline, etc. Is that the easiest/cheapest way to go abo
