This is caused by cte mis-match. The balls in the corners are short and fat. The balls near the null point are tall and more normalized. I don't remember what the zone settings were... BTU VIP98 BS was probably 22-25 IPM

Not to turn this into a used equipment war but I have a Heller 1088 4 zone i could sell for $4K in a month or so. We just got in a new BTU Pyramax98 and will soon have no use for the Heller....

how many zones? And what settings are you using now? And you won't get it exactly like the data sheet, especially the cool down.

Do you really need to have that shape of profile, why not have a gradual ramp then spike? Which paste are you using?

I have 4 of these furnaces. Give me your length, width, mass (grams) and I'll run this through our system and get you close.

Thank you - The PCB weighs 192.9g and is 314mm x 228mm. Not very densly populated.

Cheers Samir, that was a great help! I've tweaked the settings a bit to suit our PCB and it works well. Thanks again.

Check your battery back up if you have it. If I remember correctly, you may have to manually switch your wiring to by pass a dead battery back-up.

Hey Chunks, Come APEX time, I'd like to see your, uhm, "credentials" (*(wink* *wink*). Of course we still need to hit that Karaoke bar!
