Dave: In terms of heat transfer, air is 78% nitrogen, and the remainder is mostly (20.9%) oxygen (roughly the same molecular weight as nitrogen), with a bit of argon (0.9%), CO2, hydrogen, monosodium glutamate etc. So you would expect virtually no d

| I am starting a new project which involve 3 oz copper layer with 20 mil components on the top of the board and 0.040" thick copper with D2Pak on the bottom of the board. | There is anybody has experience on metal-based PCB reflow process? I guess

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

The Manncorp machines are Autotronik machines re-branded. These are Chinese built while pretending to be German, they are seemingly capable enough and do come in at very attractive price points. The FLX from Essemtec is in many ways a slicker machine

Hi, We used a batch oven from Reddish Electronics out of the UK. It was convection, and ok, but had limitations. Batch convection ovens start to heat up, so the metal of the oven is hotter and hotter and it effects the profile. So we ended up need
