Hello all, Our guys here still have some questions on the "optimized" profile which sees a more moderate ramp up straight to reflow temperatures versus the conventional profile which has a plateau at around 150 Celsius. If the optimized profile can

| I am profiling a BGA for the first time and I am seeing temperature flucuations on the ramp and cool down from the thermocouple I have placed through the pcb and under the component. I am using a 5 zone convection oven.Any suggestions on the plobl

I have a product using high temperature solder to connect terminal pins to a PCB. The board is single sided copper, no plaiting. The solder is 95% tin 5 % silver. The flux is low activity rosin. The product is a subassembly. When the product is

i am working with the noclean process and getting white residues on the bottomside of the board probably due to the wave soldering flux.i am using a no-clean solder paste and a noclean wave solder flux.The boards passed the accelerated temperature a

Ya I agree with Dean. We've done quite a lot of work with the SRT Summit2000 rework station.The results have been satisfactory, to say the least. One should however characterize the different operating parameters:namely the working scavenger air flow

Dear Folks: I am currently in the pre-prep stages of a market study that's focusing on different methods of microprocessor cooling and the market potentials of new designs. I wonder if you might be so kind as to point me to good general resources s
