If I read this correctly you have two identical ovens that were setup the same ie zone temps, fan speeds etc... when you ran the same board through each of them one showed a lower board temp. Is this correct? Is the temp of the board 7 deg. lower t

We have a Speedline Electrovert Bravo 8 reflow oven. We have issues where we get a "thermal runaway HTSC trip" error and the oven shuts down. We normally can unplug and replug a connector into the Sensor/Relay Watlow AnaFaze TLM-8 module and it sta

We agree with Wolfgang. Adding points along his line of reasoning: * Also consider placed component prescience. Sometimes, a mis-pick results in paste on the nozzle, which leads to the next component being stuck on the nozzle and not placed, which

Hey Gyver: If you don�t mind (which you don�t have any choice about, because I�m going to do it anyhow, cause it�s MY word processor), I�m going to respond genericly, but still be directed to your question. Much of the following is paraphrased from

I don't know your oven but I have dealt with high temperature ovens/furnaces before. These would be my thoughts. Change in the resistivity of the heating element due to aging. Blockage of air flow in the oven by buildup of soot/ debris in either th

Sure looks like flux residue to me and I don't know how your bare boards could be causing that unless there's something on them when you get them, and that you would notice. I'd still be looking at my own system, blowers and exhaust lines. Do any of

Hi Jaqueline, my first thought goes into the same direction, twist or warp (either the board or the BGA itself). I don�t know the SRT equipment. I�ve noticed with our equipment using a spot underheat element caused some warpage of the PCB making it

Steve, I have no influence over conn design. We paste print-reflow solder two types of connectors. One is a 50 pin IDC w/ 0.5mm lead dia @ 2.54mm lead pitch and a chamfered pointed lead tip. The other is 32 pin DIP w/ 0.36mm lead dia @ 2.54mm pitch
