Let's assume that SMT or MEMS or COB etc, is a new things and about to be introduced to the line, nobody knows about this new process and I was asked to select the critical proceses and parameter, how and where should I start?
Your first inclination is correct. You should start by asking your friends and colleagues on SMTnet: * What is that SMT or MEMS or COB etc.? * What are the considerations when processing a SMT or MEMS or COB etc.?
We�re one smart crew that won�t steer you wrong, at least not intentionally, well most of the time. At least we were one stake in the ground.
Other sources of stakes are: * Component [ie, SMT, MEMS, COB, etc.] supplier. * Process equipment technical support. * Process materials [ie, solder, paste, adhesive, etc.] technical support. * Technical helpline folk at EMPF http://www.empf.org * Archives of trade magazines [ie, SMT, Circuits Assembly, EP&P, etc.] * SMTA Knowledgebase http://www.smta.org. * Process consultants like: E Moon, W Engelmaier, L Hymes, etc. A list of these types is at http://www.ipc.org. * Fine SMTnet Archives
