My company manufactures electronic modules for the automotive industry. We have a current product that the customer would like a "heavy duty" version of. The module will have to handle roughly twice as much power as the original. A couple of compo

You need to decide what types of processes you need to run right now. What is the mix of different devices and what volume is required for each product. Are you doing a mixed technology board (SMT & PTH) or just SMT. Are there fine pitch devices (und

Jack: You should use your components promptly. Don't store 'em, only bad things will happen to them. 1 You should store all your components, not just your SMD reeled components, so they are not damaged or their solderability decreased. Check the

While there may not be any specific requirement to cleaning prior to coating, cleaning an assembly prior to coating will only serve to increase the reliability and integrity of the coating. Some residues from low-solids fluxes can interact with conf

I ma trying to get some information on possible causes and screening tests for PCB delamination. Is the main cause moisture absorption of PCB material or entrapped chemicals and or air in innerlayers that expand when expsoed to subsequent reflow and

It�s funny, the third question on this topic via "Georgia tech..." in the last few weeks. Seems on that particular forum people with the same interests are gathering or maybe they are working all on the problem without knowing about each other. Dani

Dear Dreamsniper, A big hidden cost in any cleaning system is the cost of diminished production and rework. I assume you are cleaning the adhesive stencils manually since there is no equipment cost in your formula. Manual cleaning of adhesive sten

We are reflowing ceramic resonators and are finding their tops falling/popping off when handling the pcbs during final assy. The epoxy seems to be coming off the components base and adherring to the lid. The components are "RFM resonators", case type

Richard, take a given volume and weigh it. For your parts you have already determined the aperture opening and stencil thickness and that gives you the volume for each lead of the component. This way you should be able to determine the amount of pas

50% of cost, bin it. If viable, spend no more than that time to fix. Then concess or use as is. 3) Components are more tricky. Can they be returned to supplier if deemed to be faulty? (proof?). Is/was there an in-house handling problem ? Have design
