Craig, Since you didn't share any detail regarding the component side of the board or what other components reside on the bottom side, I'm prepared to take a stab in the dark. Have you considered doing a double sided reflow on this board? Also

In our DFM guidelines for PWB layout we have discouraged placing BGAs in the longitudinal center of a PWB. We believed the increase stress through reflow and wave was not good for BGAs - probably read it or reasoned it. Now, this position is being

For me it sounds like to much paste. If it worked in former runs with the same design and stencil look for changes in your printing process, check the volume and shape of your deposit. Redesigning pads and playing with aperture size allowing for mor

Hi There, Could anyone please give me some pointers on screen printing non-conductive adhesives or where I could find the information avaliable. Aspects such as printing parameters, ideal stencil design and a general overview. Do already have a part

GEOMETRIC DIMENSIONING AND TOLERANCING (GDT) Using and applying GDT to printed circuitry and assemblies is very much like applying it to any other design for manufacturing (DFM) or design for assembly (DFA) requirement using concurrent engineering (C

All, Does anyone know a good book, software, Check list etc. to analyze and develop the whole electronics assembly and manufacturing process ? I mean, not only SMD-process but also unit assembly and final assembly ? I assume that ultimate goal in t

In addition, consider: Solder paste selection, including clean or no-clean is also quite important. This can vary from application and is somewhat process dependant (what works best in the environment). Relow profile. A must for many reasons. And

There is not enough time in the day to reliably hand solder these connections. Go buy yourself a solder fountain and spare yourself and your company the misery. Check the fine SMTnet Archives for sources of supply. Everything has a price. A solde
