Ron, have a look at http://www.fda.gov/cdrh/dsma/cgmphome.html It would be a nightmare, if your plant is not structured to support it. It's a huge pain in the fanny even when you (alledgedly) are. I'm not sure what you're pursuing, but if you're c

Frank, Your initial question about temperature profiling is a critical point to a good wave solder process. Especially if you have a No Clean flux. As recommended by many in the thread above, get the Process Data Sheet for your flux (this is not the

I am having problems achieving correct pre-heater temperatures with our Hollis solder wave. Our original "Verification Golden board" program uses a conveyor speed of 5ft per minute and pre-heat temps of 300, 350, 400 respectively. Our "golden Board"

I have used one in the past and wish I had one now. Is that enough input? We had great success with this machine. The large lower preheat and board supports worked very well for large thin boards. We never experienced any problems with this machi

Hi, I would get a KIC profiler, and put thermocouples on the PCB to get a correct profile. You can enter your specs into the software, and it will give you a simple percentage letting you know where you are inside your process window. 0 is perfect i

No question that metal retains a lot of heat (slow to heat up and slow to cool down). But again in a batch oven, it mainly boils down to the heater. I know, until you see proof you are skeptical. I think by posting a url to product specs will

Hi, I have seen demos of these scopes, and don't think they really show you very much. If you profile your board right, and drill up to solder a thermocouple onto the inner balls of the device so you really know your getting a good profile, I don't

Marc, Topside temperature is one of the most critical parameters for a successful solder process. Temp stickers are OK to use but won�t tell you the temperature in tight areas. The temp gun like Jay suggested is what I use as a quick indicator. (Rayt

Hi, I am having problems reworking a lead free PBGA (23mm x 23mm, 1mm pitch). The board is relatively small (5" X 4" X 0.063"). During the removal stage, a thermocouple was placed at the solder ball level (between the board and underneath of compo

It always surprises me how many variations there are for profiling and controlling your ovens, and the thing is most of them are fairly valid. Here's yet another option: Your board profile needs to be specific, 2 boards can look identical but have ve
