I'm looking for information (links) to pad design and layout spec's for different sized passive SMD's. To be specific, 0603, 0805, 1206 and 3216 sized parts. I'm most interested in finding out about land spacing between two parts. What is accepabl

Dan- We here do double sided reflow: we place one side and reflow....place the other side and reflow. On the second flow the underside of the PCB- we will reduce the bottom side preheat. fortunatly for us the largest component we only place a 40pin P

You may check with the TDS of respective "active parts" IC manufacturers for their recommended no. of thermal cycles permissible in the reflow process. Last I checked 3 cycles for our RF-apps IC was still allowed. For 48pin-QFPs this can be allowed

Do any of you guys have a list of parts that cannot survive hanging upside down during reflow soldering. As our board designs become increasingly dense and higher speed, we need to use all available pcb real estate. This means locating parts we hi

Dan, We, do alot of double reflow. Your right we typically see alot of the standards components, SOT's, SOIC's, Chip stuff. The largest we do with out adding epoxy is some 32pin PLCC's. We have several assemblies were were doing PLCC44's, Sockets
