Steve, We do not currently run BGAs, but I have been told by a CM we use that does BGAs, that our Heller 1500 (5 zone) oven has an insufficient number of zones to properly reflow a BGA. Anyone else have an opinion about this it would be appreciated

Howdy Bolo, I see. I currently run a 5 zone 1500 Heller, It's a very nice reflow oven and one of my favorites. Hopefully in July we will be getting in our 1700 from Heller. These reflow ovens (used) can be had for a pretty decent price at least in

Jay - I read your report and was interested to see that you ran your evaluation on a Heller 1500 5 zone. We have been hearing for some time that a larger machine (7 zone min)with higher temp heaters and fan motors would be required. Is yours a "hi t

Eric, Protective sleeve? The sleeving protecting the wires of the thermocouples? I bought mine direct from Heller. I think it was $90 for a set of 3 (my oven uses 3 thermocouples). They are close to thirty feet long (I'm guessing...they're much

Use Mydata. I've built huge backplane boards, round boards, 1/4" thick boards, 1"X24" boards, 1"X1" boards, L-shapes boards; all without any carriers or tooling. If you buy a MY15 you can increase the board size to 5'X2' (60"X24")... As for ovens,

Hi everyone. I am now faced with a problem on soldering PBGA. At first, I ran the board (FR4, 7" X 10" with 12 layer) at Peak Temp: 205 C and 54 seconds above 183 C. After reflow, I found several cold solder joints and one ball without second collaps

Eric, I haven't used this oven; but, our Heller has built in profiling. Essentially, attach the thermo-couples to a board, and the appropriate point on the oven, and run a board (without parts). Your paste manufacturer will have published a reco
