Why Is the Throughput Rate So Critical in SMT Patch Processing?

In the field of SMT patch processing, the throughput rate is a crucial indicator for measuring production efficiency and product quality. The throughput rate directly reflects the technical strength and craftsmanship of the patch processing plant, and is even more closely related to the profitability of the enterprise and customer satisfaction. Here, Charmhigh Electromechanical would like to discuss why the SMT patch processing throughput rate is so important. Interested friends, let's take a look together.

The throughput rate, also known as First Pass Yield (FPY), refers to the number of good products that pass all tests for the first time among 100 sets of PCBs put into production. This ratio visually demonstrates the qualification rate of products from production to shipment and is a key indicator for evaluating production line efficiency.

However, improving the throughput rate is not an easy task. Factors such as material quality, solder paste selection, and employee quality may all affect the throughput rate. To optimize and improve the throughput rate, we need to focus on the following aspects:

Firstly, optimize the stencil design for PCB circuit boards. The rationality of the stencil design directly affects the printing quality of the solder paste and further impacts the welding effect. Through refined design, reduce adverse phenomena such as solder paste offset, tip pulling, and collapse to improve welding quality.

Secondly, select the appropriate type of solder paste. Different products require different types of solder paste for printing. Choosing the right solder paste can ensure welding quality and increase the throughput rate.

In addition, adjusting the squeegee angle and pressure of the printing machine is also an important means to improve the throughput rate. Reasonable squeegee settings can ensure the uniform distribution of solder paste and reduce welding defects.

Finally, pay attention to the temperature curve of the reflow soldering. Adjust the preheating time and reflow heating curve according to the product characteristics to ensure that the welding temperature meets the product requirements.

Improving the SMT patch processing throughput rate requires multiple approaches, including optimizing the production process, improving employee quality, selecting suitable materials and solder paste, and other measures to ensure the stability and reliability of product quality. Only in this way can a company thrive in the fierce market competition.
