Thanks for all the replies. Rob . . . that's what I was looking to get feedback on; to see if others can program their reflow ovens so that double sided boards only reflow on top during the second pass. Our oven does have an edge belt conveyer so t

Hi CKH, Here's some things to consider: 1) Moved by obstruction in/entering oven, such as nitrogen skirts 2) Incorrect air pressure/air leak in oven (large surface area on component) 3) Reflow temperature too hot & electrolyte/air in cap is expandi

Q1. After reflow some boards start producing bumps/bubbles which damage the internal layers causeing PCBs failed in Electrical-testing. How can I eradicate this problem from my assembling process? A1. Find a proper board supplier. Q2. If SMT compon

hahaha! LISTEN, everyone knows that oven get dirty. They need periodic cleaning. So if you run lead boards thru your oven you will get lead dust and residue in you're oven. If you want to be truely lead free you need to get all the lead outta of

Well, I don't know if you want to muck around this much, but I bought a GE (Chinese made, of course) toaster oven with convection fan. Nice big glass door in front, you can use it in bake, broil, toast or convection oven mode. The only thing missin

Rob, Had that issue early on when we hooked up our Heller. For us, the problem turned out to be the serial communications port on the computer. I can't say we had the black screen, but, we had comm errors. I'd check the following: 1. Cable betwe

We used to use an APS Gold GF-120 before we went lead-free and the HT version came out. It worked fine for low volume and proto runs though not as much control over the profile as an oven with more zones. We actually had a batch oven from Bomir befor

Make sure that the 40 degree C oven is getting to less then 5% RH inside especially for any applications where you need to dry components....it may surprise you that many ovens set at 40 C will have an internal RH of @ 20~30%....and that is not dry e
