I have been reading a good deal about IMC (purple plague in particular) in gold wire/aluminum pad wire bonds. My company uses ultrasonic wedge bonding, and for the most part all of our bonding is gold/gold, however we have one particulr part that has

Hi Lads, Thanks for all of the replies. To answer a few of your questions..... My wave is a Hollis PT500N. It has 3 zones of pre-heater rod elements. Each individual element (601195-01) is 500 watts. There are 16 elements per zone so 8 Kw per zone.

It makes sense. With temperature viscosity will change, and more liquidus material will flow better.

Selective Soldering Frames can pull large amounts of heat from the solder wave at the point of contact, effectively lowering the temperature of the solder at the solder joint. You should confirm the temperature of the solder joints by running a therm

Hi, There is one thing missing still, you must put a TC from the bottom side of the BGA by making a hold on the test board at the TC can measure the temperature at exactly the middle of the BGA. You should be able to the dual time and peak temperatu

No matter in selective soldering or wave soldering process, higher pot temperature and longer wetting time can increase IMC thickness and joint strength(reliability), but as Daivf said, you need to care if the DIP component and bare PCB was damaged b

I'm trying to find information/articles describing the effects of temp and humidity on solder paste. Just recently we have gone through a change outside temperature and humdidty and have notice solderabilty problems with smt boards.

Hi, Has anyone done some research (measurement/simulation) on the effect of PWB vias on solder ball temperature of the component? Would this have some effect on solder joint reliability especially during power cycling? Any comments will be appreciat
