The correct reflow process:

  Reflow soldering technology is not as simple as many people think. Especially when you are required to achieve zero defects and weld reliability (life) guarantees. I can only share my experience with you for the time being.

 

  To ensure a good reflow soldering process, the following should be done:

 1. Understand the quality and soldering requirements on your PCBA, such as maximum temperature requirements and solder joints and devices that are most needed for life;

2. Understand the soldering difficulties on the PCBA, such as the portion where the solder paste is printed larger than the pad, the portion with a small pitch, and the like;

3. Find the hottest and coldest point on the PCBA and solder the thermocouple at the point;

4. Determine other places where thermocouple temperature measurement is required, such as BGA package and bottom solder joints, heat sensitive device body, etc. (use all temperature measurement channels to get the most information)

5. Set initial parameters and compare them with process specifications (Note 9) and adjustments;

6. The soldered PCBA was carefully observed under a microscope to observe the shape and surface condition of the solder joint, the degree of wetting, the direction of the tin flow, the residue, and the solder balls on the PCBA. In particular, pay more attention to the welding difficulties recorded in the second point above. In general, no welding faults will occur after the above adjustments. However, if there is a fault, for the failure mode analysis, adjust the mechanism to match the upper and lower temperature zone control. If there is no fault, decide whether to make fine tuning optimization from the resulting curve and the solder joint condition on the board. The goal is to make the set process the most stable and the least risky. When considering the adjustment, consider the furnace load problem and the production line speed problem, so as to get a good balance between quality and output.

 

The adjustment of the above process curve must be determined with the actual product. Using a test board for the actual product, the cost can be a problem. Some users assemble boards that are very expensive, which causes users to be unwilling to test the temperature frequently. Users should evaluate the cost of commissioning and the cost of the problem. In addition, the cost of the test board can be further saved by the use of fakes, scrap boards and selective placement.
