A little more heat energy to get them to the optimal temperature during reflow, but a side benefit of less warpage due to the more even spread of heat through the device during the heating. Drill the board and do your TCs and profiling as normal. Th

Hi, I was just hired on and put in charge of the wave machines. One lead and one no lead (lead free). My company currently does not have a wave profiler. He wants me to jury rig the re-flow profiler to work on the wave. I really think we need one ma

Vapor phase soldering systems by Asscon are characterized by special designed heating modules. The thermal mass of the heating modules is designed so that a completely delay-less and direct regulation of the heat/flow/energy transfer to the soldering

Hi All, We have purchased an Ersa Versaflow selective solder machine, and I am looking in to profiling upon the machine. We currently have a process for profiling our wave with a WaveRider system, this we use to gauge that the machine is set up cor

We have a PCB to be populated using reflow soldering. The board contains lead free BGA device(11x11, 1mm pitch ) and Standard SMT devices which are not lead free. Since profile temperature is different for both devices, our contract assembly house is

Sr. Tech, As far as I’m aware, most if not all, manufactures of thermal profilers offer K type thermocouples as a standard for profiling in the electronics manufacturing industry. In my decades of experience in the reflow and wave solder industry, t

There are many profilers(physical devices) on the market. Most of them have software that makes predictions based on information about the paste, oven model...., but I wouldn't trust the predictor as on your boards you will have different parameters

We are in the process of launching a new product and found reflow solder issue with one of the inductors. I have set oven profile to paste specifications. I just finished profiling with thermocouple under problem component. All other components ex

Hi Bartel , 1.1 Profile Solution to Cold Soldering Cause for Cold soldering The peak temp of reflow is too low. The preheating temp is too high and it takes too long Solution Lower the preheating temp and increase the peak temp in the reflow zone
