The longer the oven, the better. You will have much more capabilities in creating the precise profiles the way you want them(with10-12 zone oven). I have worked with ovens from 2 to 12 zones and the difference is huge. In my opinion try to get a 10zo

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

Thanks for your input Rob, Our operator does not profile pcb's which so far we have not had issues that could be attributed to his oven settings. We may be running a pcb with a BGA on it and I was concerned about our lack of profiling. I have spent q

yes this paste is a pain in the paste.... there are very few reasons for solderballs, component to pad ratio and placement.... solder paste control, using a mixer, not hand mixing, checking viscosity and temp..... or simply and bad profile and your

Need more information. BUT if your strictly considering just the paste change. I would imagine your changeover would be little to no different than changing to the second board if you were using the same paste. Maybe take extra care cleaning your sq

Hi, As stated by everyone ,you really should have a Profiler and be checking the oven at least once a week. As a quick fix to Identify if you are reaching reflow temp at all, I would recommend that you buy some Thermal Indicators (temp. stickers)th

Hello, I have 4 BTU Paragon 150s in the factory where I work for. One of them has a weird behaviour: in order to get the same thermal profile as for the other ovens, I have to increase a lot all the temperatures. I think there is something wrong with

The surveyor is a a plate that I use to "survey" or verify the oven on a weekly basis. The data logger or profiler is the actual unit that follows the board through the oven to take readings. I don't think the zone thermo couple that measures temp a

We don't use the connector that is giving you soldering problems. Regardless, no one here is taking bets that you'll get pay-back from increasing the length of the locking pin. If it makes you feel any better, we'd bet against a 4-40 flat head and

And digging a bit further, are the opens at the device level (all the solder on PWB pad, none on device pad) or at the PWB (similar to pillow defect?) After answering that, I would start thinking about(in this order)paste print quality and consisten
