For a few thousend boards, I would look into some automation. In order to get the components off the boards you could run the boards through the reflow oven with the cooling fans turned off. When the boards come out of the oven the solder is still l

Hi, a did a study on a FMEA for a government project, and I do not relish going thru that S**T again! Aye laddie, as a QA skirt i must protest! its called a kilt, not a skirt! *grinz* and we dun keep FMEAs in the folder cabinet, there's only room f

what are your grading criterias? All of these work pretty good but have differences in the "bells and whistles" I like the Air-Vac DRS24 (no exp. with the 22) because of the large under heater and thermo-couple control. but it is very slow and costl

I am not familiar with the VIP98, but I have worked with other BTU models for several years. As I have posted in earlier threads: there is absolutely no way to tell whether your profile is correct unless you attach thermo couples to your board and ru

What are your temps at the locations that you are having trouble with. We cannot tell anything by the zone settings of an oven. We need max temp, how long above liquidous etc.. a lot of times this symptom is due to too long of a soak at too high o

I have done few thermocouples using high lead solder, silver epoxy that is used for die attach purposes and some X - non conductive material. Though all materials show a slight variation in temperatures (3 to 5 degree C), the dwell time at peak is qu

When not practical to drill hole into pcb to profile here is what I do and seems to be just fine. place thermo into area underneath BGA and let her rip, you will not be in the ball/solder joint, but the temp difference as long as you are in the arra

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

The entire oven is clean there are no blockages and the heater plates are brand new. I have worked with Vitronics technical support and gone through this thing with a fine tooth comb. I have even gone as far as to compare the exhaust and intake cap c
