So, I made a spreadsheet-you can download it for yourself. The below temperature profile for moisture sensitivity characterization is based on the IPC/JEDEC. They only give a bullet every 25 seconds, and you even have to guess those temperatures! It’s difficult to “eyeball” the interpolated 10-second intervals here. Here’s an example from MG Chemical for their 4902P low-temp, lead-free paste: Burn-in a test board with thermal shock and mechanical shock to check the board’s reliability. Check the solder joint quality, PCB and component status. Unfortunately most solder paste datasheets don’t specify at 10-second intervals rather, they specify times and target temperatures. Reflow the board and measure the real time thermal profile simultaneously. Reflow soldering is to achieve a good reflow soldering effect by adjusting the temperature curve of reflow soldering. Why the the reflow oven profile can reflect the quality As to this question, you can find the answer in the following contents. You specify a target temperature at 10-second intervals. Reflow oven profile is the important tool to reflect quality. ![]() The main thing I did was install the replacement firmware written by Unified Engineering, and replace the masking tape (!) with kapton tape.Įither firmware allows you to configure two custom profiles. This is a reflow oven that can be bought fairly cheaply, but because the manufacturer cuts corners in several places, you have to do several modifications to make it usable. Powered by ECD, this innovative software package provides three levels of process control from Reflow Oven CPK, to Process CpK and Product Traceability, this software ensures that all parameters are optimized and SPC reporting is fast and easy. For a precise measurement of the temperatures during a reflow soldering. I am the proud owner of a new-to-me Puhui T-962. The two most common types of reflow profiles are the ramp-to-peak profile, also called ramp-to-spike or tent profile and the soak profile, or ramp/soak/spike profile. measuring of the temperature profile during the lead-free reflow solder process.
