I Kyung: I'm not sure if we are working with PIHR but we insert some pines in a PCB with a pin inserter machine, after that we run this pcb in a screen printer and put over its solder paste, and then run in a chip shooter and then IC placer and f

Ron:It�s tricky to get what you want with this foamfluxers espacially using pallets. They got to be cleaned regularly. Most of the time excessive residues are removed using brushes which adds another process step. It should be better using a sprayflu

Hey Gyver: I was just spoofin' ya about the deionized water (DI). Water of any type will probably make your solder connections go white. I posted your question to Dr. Lee on the latest OnBoard Forum. I suggest you check his responses. I short he

Hi Steve You really didn't tell us what is going wrong. Not enough heat to melt this hi temp solder (290C/554F)? Too much heat and burning up the pad/board? Thermo falling off? (remove all the original solder) You won't find Loctite 384 all that remo

Hey CK: I do not know who makes the "orange cover that goes over a WinKic datalogger". Maybe someone at KIC can give you a source. Further, John makes good points. Have you talked to your power brick whatever supplier? Alternately, consider usin

I recently have been examining multilayer board failures. They are the classic inner connection failure between the foil and the through hole plating which I have not seen in many years. Has any one experienced any issues recently specifically relati

Simon: Books that will teach you enough about printed circuit board fabrication to be dangerous, in no particular order, are: * Coombs "Printed Circuits Handbook" McGraw-Hill * Jawitz "Printed Circuits Board Materials Handbook" McGraw-Hill * Macleod

Our company is putting a BGA/CSP package assembly line together. We have been studying different assembly houses reliability (short and long term) monitoring programs. I was wondering if some of you who use BGA's/CSP's for your MCM's and Hybrid's

Dear all, Thanks for your comment! Dave, your suggestion is very useful. I can find several good machines at there. Thanks! John, your curiosity is quite normal, as I also have no idea of the board. It is a new model. We haven't got the boards yet,

Jason, where on the board is your connector?, front / back / middle? and where it on the PCB that you don't have issues with? Thief pad's are basically dummy pad's taht you have after the last set of pin's on the component are are used to draw the
