Wave Solder Process Control

By: thomas
Wave solder process is the most important factor in determining the quality of the printed circuit boards manufactured. It decides the quality and the performance of the printed circuit boards manufactured. It is a quite necessary process for the manufacturers in this business. All the printed circuit board manufacturers keep a sharp watch on every single process taking place in the printed circuit board manufacturing through the wave soldering process. The monitoring or we can say that the optimization process for printed circuit board manufacturing plays a key role. The controlling of the wave soldering process is also a very important factor in the printed circuit board manufacturing.

The controlling of the wave solder process is done by the wave solder optimizer. Optimizer is the most accurate, easy-to-use and well-liked wave solder process device in the world. It is the only device which straightly optimizes the vital constraints of the wave solder process: the straight interfacing of the board with the wave. The optimizer goes through the wave soldering machine same as the boards do.

The board-wave sensors at the base of the device observe the solder wave just like the lead on the assembly. The on-board temperature sensor card permits the daily thermal profiling process. A particular Flux Distribution Window gives you the information on the distribution of the flux. It provides the information on the flux distribution, like whether the flux has been applied evenly or not and like whether the flux has been applied at the right place or not.

Optimizer provides the completed data for the wave soldering process, the data provided by the wave solder optimizer comprises of the board wave interaction, Board to Wave Parallelism, Dwell Time in the Wave, Immersion Depth in the Wave, Contact Length in the Wave, Conveyor Speed Measured Independently, fluxer performance, Thoroughness of Flux Distribution, Evenness of Flux Distribution, Weight of Flux Applied, temperature data (Top-Side & Bottom-Side), Preheat Temperature, Maximum Temperature, Maximum Preheat Slope, Delta T (max temp - preheat temp), Maximum Slope Over Wave. These all data provided by the wave solder optimizer helps in making the process of the wave soldering even more efficient and improved.

Methods which were used earlier cannot give dependable measurements, accurate repeatability or genuine optimization for the parameters involved in the wave solder processes. The same is applicable for the devices that try to calculate just one surface of the board's interface with the wave, like a glass plate or even a temperature profiler. The consequence, in-spite of the real imperfection rate, overstates the production costs, damages the assembly quality and is also a factor of frustration for the staff.

The optimizer's accurate data facilitates you to spot the correct optimal constraints for a PCB assembly. Connection of the optimizer data with the board quality will illustrate which blend of dwell time, immersion depth and contact length causes the minimum defect rate for every printed circuit boards soldered by you. In this manner the wave soldering controlling is done by the wave solder optimizer.
