Hi First of all you have to respect the dwell time and the time after the reflow at peak tmeperature.(225�C for Pb and 235�C for Pbf) You can find the reflow profile from manufacturer for majority of parts designed for reflow sodlering. In general t

Sal, This is a common problem experienced by several OEM's. It all comes down to heat. This is why the problem is corrected on your repair unit. I would suggest using a Slim Kic or Data Pac (mole) to thermal couple the IC prior to the reflow oven.

This sounds like something the saleman of your new Vitronics oven should be happy to help you sort through. ECD [and probably other profiler supplers] provide software for playing with [optimizing?] recipes. In it, they allow you to select from a v

Your oven no doubt compensated by reducing energy to your heaters so it might not be as bad as you think. I'd be more concerned about even heating than over heating. My opinion is that an out of calibration profiler result is better than no result

You answered your own question you get what you pay for. $3500 dollar’s for a small oven is not unreasonable. I have seen small proto type ovens do a pretty good job on basic circuits. If you are getting into high density BGa stuff and multi layered

Does the flickering go away once the oven reaches its set temperature? It will draw a lot more current while its warming up then when its running. Are your lights running on one leg of the same 415 VAC circuit? Reflow ovens are mostly resistive loa

| Cpk's on top flight ovens (e.g., Conceptronics, Heller, Electrovert, Vitronics) vary wildly, from 1 to 2+, between different supplers. The suppliers don't seem to understand Cpk's. A supplier's rep whose oven has a Cpk of 1.0 told me: | 1. Cpk's

Is the soldering community narrowing down the list of possible Pb-Free alloy candidates for oven-reflow SMT?
