During the PCBA processing process, one end of the electronic component will be lifted up, which is what everyone calls the tombstone phenomenon. So what exactly is the cause? Is there any solution?

The development trend of SMT is that components are getting smaller and smaller, and the assembly density is getting higher and higher, thus realizing the characteristics of small size, thinness and lightness of electronic products. If PCBA processing is classified by application, it can be divided into the following categories.

During PCBA processing, there are many production processes and many quality problems are prone to occur. At this time, it is necessary to continuously improve PCBA welding methods and improve the process to effectively improve product quality.

Introduction to the whole process of patch processing
Single-sided assembly: incoming material inspection + silk screen printing + solder paste (red glue) + patch + reflow (curing) + cleaning + inspection + repair

Automatic optical inspection (AOI) uses high-speed, high-precision visual processing technology to automatically detect various mounting errors and welding defects on PCBA. AOI optical inspection is a very important inspection link in SMT patch production. So how much do you know about AOI optical inspection?

It is said that quality is the lifeblood of an enterprise, and inspection of incoming materials is essential. Carry out sampling to inspect the quality of raw materials sent by suppliers, and make judgments to accept or reject the batch of products. So what should be tested for incoming materials during PCBA processing?

Surface mounting technology (SMT), also called surface mount technology, is a new generation of electronic assembly technology that can achieve high density, high reliability, miniaturization, low cost and production automation of electronic product assembly. So what are the advantages of SMT technology?

As we all know, PCBA welding includes wave soldering, reflow soldering, and soldering iron. Everyone’s processing techniques are basically the same, but the welding quality is very different. Why is this? What affects PCBA welding performance?

The process flow of SMT patch processing in Dongguan is complex and cumbersome, and problems may arise in every link. In order to ensure product quality, it is necessary to use various testing equipment to detect faults and defects and solve problems in a timely manner. Then in SMT patch processing.

SMT production process will implement strict process management, but in our actual production process, defective products that do not meet the process requirements will appear. These defective products are separated through quality inspection for analysis and repair. So what testing methods do PCBA processing plants have?

In the PCBA processing process, to ensure a high product qualification rate, in addition to strictly following the requirements in production management, production equipment, and production technology, the early PCBA design is also a very important link. So what should you pay attention to when designing PCBA?

Everyone knows that a powerful PCBA manufacturer must have R&D capabilities and production capabilities, be able to complete delivery plans according to quality and quantity, and at the same time solve various industry problems and design the most suitable solution. Therefore, the production line of PCBA manufacturers must also be complete, so do you know the composition of the SMT production line?
