This can be seen on leaded soldering also as well as LF (worse with LF). To reduce this you can look at your stencil and profile. Printing a cross-hatch deposit can reduce the voiding as it allow gasses to release when in reflow - thats the theory

Hi, I have done conversion from SAC387 to SCS7 with great results on process improvement with low cost. I see only the melting point is higher but still the solder pot temperature settings is 250�C to 260�C as SAC. If somebody think the temperature

Randy, Thank you for the acknowledgment. The IF2005Mz is a solvent based flux (not water soluble). I agree with you that the original IF2005M had a very narrow process window. In 2000 we modified the blending procedures and blending equipment which

15 C. it's very hard to decrease the Delta T. and the socket temperature always the lowest one because of it's large ,partly metal composed body.is there anyone can share with me the profiling experince of P5 socket? or any suggestions will be greatl

To answer Gary's question: Gary, you will need a production board, thermal profiler, flux vendors product data sheet on the flux you intend to use, maybe your wave vendor service engineer or wave solder vendor contact (unless you know your wave) and

Wow, all this BTU talk brings back bad BTU memories. Yes, the VIPs are good ovens, but the TRS series and Paragons were bad. TRS had air amplifiers - nuff said, while the Paragons had long spell of bad motor bearings because of design issues. Neve

Agree!! Where is Your thermocouple-probes attacded and can we get the info from this? Delta-T of the comp. is very, very important! The single most important smt-process step is the profiling/recipy and as a result of this, this poor package will cor

Drill a hole through the board (or the BGA) and set a thermocouple into the center of the device (in the X Y and Z dimensions) and run your profiler through the oven until you get the temp you need in the center of the BGA. Attach a second thermocoup

Hello all! We possess a speedline electrovert omniflo 7 reflow oven at my site. Last week we examined how the solder profile was affected by fan-speed and by providing the soldering process with compressed air(O2) or nitrogen(N2). We also ran the sa
