Minimum gap between 0402 parts

Electronics Forum | Mon Sep 18 11:55:35 EDT 2000 | Ricardo Fuentes

Hi! cold someone advise me about the minimum gap allowable in between 0404 parts. The minimum distance is because of the behavior on reflow, the re-work difficulty or anything else. Thanks

I need advices as to how a gap between the bottom of an LED (1209-package) and the PCB can be controlled on a small rigid-flex PCBA? The problem that we experience is due to tight tolerance in the design of our molded housing in which this PCBA is as

Sure would. We discussed applying the glue on the sides rather bottom of the part. Hopefully the seating of the part during P&P helps push it down. Certainly there will be still some gap as some of the glue will be under the part. Each experiment off

Does anyone know of any resources that will come into our company and provide a gap analysis between the RoHS requirements and our current processes and proceedures? We have done a lot of work so far but we want to make sure there isn't something we

Most likely there is movement during reflow. How about conduction oven over convection oven for reflow? This is a small PCB with the LED sitting on a Flex-Rigid extension from the PCB. I was thinking if the stencil aperature for the LED was to be cu
