Could anyone give me a basic profile temperature settings for a conceptronics 7 zone oven and speed? I have the first couple of zones ramped up to get to the soak temperatures. Is this correct or should I start out with low temperatures and graduall

* Try 1.5C / sec from RT to 165C * Hot soak at 165-175C for up to 2 minutes (I'd start with 60 seconds flat soak.) * 60-90 seconds TAL (I's start with 60) * 230-240C Peak. Thanks, Mario

Hello all, I am having difficulty with an OmniExcel 10 oven. Zone 5 upper will not hold setpoint = 165C (it typically runs ~10C higher). Here is what I know: 1. The machine is not turning on zone 5 heat when temp is too high. 2. Zone 5 lower is

52In/48Sn solder has a melting point 118C, and can be reflow processed at temperature down to around 165-170C. The material is very soft, very low in shear strength. It is relatively ductile, can be stretched to about 2-3X of Sn63 in elongation. Amon

If you lay a flat edge on the PBGA, it is visibly warped? How much of a warp? 0.001, 0.010, 0.050 what? What is your pcb temperature just prior to entering the spike process (zone or step or what ever you call it)? Is it between 165 and 175 C?

I would contact your PCB supplier, they usually have some type of software for panel optimization. Each shop potentially uses different size panels so it is a good idea to ask them what they are using and go from there. Keep in mind that there are

VIP 98, I believe that's a 7 zone if I can remember 6 years ago. Try 150, 165, 200, 235, 235 and 235 (top and bottom temps) with a belt speed of 35 inches per minute. This should get you in the ball park depending on the size of your board.

What sort of foils are you talking about? Handling VG stencils isn't exactly tough, they're a bit more flexible than standard tube frame, but nothing horrible. Pair it with a good storage solution and you're set. I'm able to store 165 stencils i
