Hi everyone, I just installed a batch oven in my shop. It;s an older Advanced Techniques PRO-90. I need to know what a good and simple profile is for it. I want to run some simple double sided boards with 63/37 no clean paste. The machine of

Your solder paste manufacturer should determine the time. As far as temperatures those will very with each board. Creating a profile comes down to trial and error, there are some nice tools that help, the MOLE profiler is one, but there are just wa

It is always a good idea to heat the entire board to 100C to 140C prior to reflowing the site to be reworked to reduce warp and localized stress. (Thermal uniformity of the preheater is key here). For a BGA, the laser is programmed to heat only the

John: The 180 Tg point is a sweet spot for obtaining heat resistance, cost effectivly. These high technology boards provide good thermal resistance for wire bonding, direct chip attach, and BGA mounting and rework. Since these boards are harder th

Dave, i tried reflowing bare boards with only solder printed on em and no component placed. we still got voids as same as when components were placed. so atleast one of that theories(voids due to component/component placement)could be considered to b

Thanks everybody for the help! We are still working on the bottom side, but the top side solder balling seems to have gone away for now. We flattened out the middle soak zone of the profile, so that rather than an even ramp up, the board heats quick

What is the rule-of-thumb on wave profiling Ceramics? I've used 2 methods: 1.) putting the T/C on the lead, and get a pretty good delta (within 50-80 deg. before hitting chip wave), well within manufacturer's spec. 2.) Right on the part body.
