In answer to your questions. (1) pls can any body throw some light on the reflow profiling? Reflow profiling is the process of confirming that you PCB's that pass through your reflow oven are produced within specifications provided by solder paste

183C, 60 +- 15 seconds). The quesiton to use a straight ramp or soak profile comes down to the product your are soldering. The key is to get the whole assembly at the same peak temp (minimized delta) and same TAL for effective formation of the so

Hi Frank, we're still going to go with FR4 as our prefered material. Our board thickness is .062. We use an on shore and off shore vendor. Prototron I believe offers an immersion tin and excellence in china? offers an immersion tin finish. We fou

First and fore most is to find your paste manufacturer spec sheets. Read it over several times and let it all sink in. Then call them with questions as they want to keep your business so their engineers want to help you use their product. I assume y

| 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 profi

Greg, The best advice that I can give you is a PBGA will respond just like any other surface mount package. There may be a 5 degree delta between a PBGA 356 and a QFP208 but the two respond very similarly in the convection reflow environment. CBGAs

Cooling may require muff fans positioned over that output conveyor of the oven.

As we have vitronics oven(SMR610A) made in december 1997,which has 5 heating And 2 cooling zones. we just want to confirm that is there any possibility of damage oven parts with long run for soldering of lead free components in this model? if anyone

Does anyone know of any good profile prediction software for free, trial or on the market that is not coupled with hardware. We want to specify the environment, paste, board and oven etc variables and have the software suggest the best cavern temper
