Hi All, We just started build a new product and I am encountering many non-wet rejects in our new product. I need help on what should I look into to improve our Yield. Please see below back ground 1. We are using DEK Infinity as printer. 2. We are mo

We're looking at redesigning our stencils to facilitate better (well, it's pretty much non-existant, so any improvement is a big leap) release from fine pitch apertures. Currently we have perpendicular walled laser cut apertures. We'll be having

Hello Amol, I continue to be amazed at the surprise engineers have on discovering that a non-eutectic alloy such as SAC305 displays micro-cracking and rough joints in a soldering process. There was a reason the electronics industry chose to use eutec

Hi Bob, The weight of the TBGA is heavier then PBGA due to the Stainless steel heat sink. I have tried run them through the oven without paste. Due to the high lead content( 90Pb/Sn10), the "solder: did not melt. Still see the misalignment issue but

We chose the MPM over the DEK. We did real world comparison in our factory with both machines almost side by side last year. MPMs offer a real windows based software that basically takes the operator out of the equation. Besides the basic screen p

| During inspection and test we find leads which do not get soldered. Some are because of insufficient paste, but with others everything looks right. This will only happen on 1 to 2 pins, and it is not isolated to a specific type of ic or location o

| We have carried out some experimental work, in conjunction with DEK. Instead of dispensing adhesive for SMD components onto the bottom side of on of our PCBs, we have looked at the possibility of screen printing the adhesive. Because, at the stage
