1. Printing equipment For double-sided mixing, because there is already a welded SMCSMD on the THC component surface, the flat template cannot be used to print the land, and a special three-dimensional tubular peripheral printing machine or a spot welding machine is required to apply the solder paste. 2. Reflow welding equipment When welding THC. […]

In PCBA processing, there are several key points in the whole process of reflow and reflow soldering. ① The reflow soldering curve should be close to the original soldering curve. The hot air reflow soldering curve can be divided into four areas: preheating zone, immersion temperature zone, reflow zone and cooling zone. The temperature and […]

The efficiency of SMT patch processing has many aspects. For example, if the overall production volume is constant and the number of SMT patch production lines is large, the production speed can also be increased. However, the operating cost is also increasing. Nowadays, the fierce competition in the electronics industry is unimaginable. In the case […]

Some details in the SMT placement process can eliminate undesirable conditions, such as incorrectly printing solder paste and removing solder paste from the circuit board. Our goal is to deposit solder paste at the desired location. The misalignment of dye tools, dry solder paste, stencil and circuit board can cause unwanted solder paste to be […]

People in the industry know that there should be no food or beverages in the pcba work area, and smoking is prohibited. There are actually many skills for pcba OEM materials. The editor of Dongguan SMT processing factory will take you to take a look. pcba foundry processing skills 1. When the solder paste is […]

The PCBA manufacturing process involves many links. The quality of each link must be controlled to produce a good product. The general PCBA is made up of: PCB circuit board manufacturing, component procurement and inspection, SMT patch processing, plug-in processing, A series of processes such as program firing, testing, and aging, the following Dongguan PCBA […]

(1) Electrostatic safety workbench: It is composed of workbench, anti-static table mat, wrist strap connector and grounding wire. (2) There should be more than two wrist strap joints on the anti-static table mat, one for operators and one for technicians or inspectors. 3) Plastic boxes, rubber, cardboard, glass and other debris that are prone to […]

1. The components on the pcba board must not be missing parts, components are inserted reversely, and components are inserted incorrectly. 2. When plugging in components on the pcba board, one side cannot be high and the other low, or both sides are much higher at the same time. 3. If the PCB is horizontal, […]

At present, all operations and production processes of pcba manufacturing companies from raw material procurement, production and manufacturing, to product sales and circulation are becoming more and more data-based and intelligent. The continuous accumulation of data and the continuous development and maturity of data algorithms and models provide opportunities for artificial intelligence to integrate into […]

How does SMT processing factory ensure the quality of SMT processing Some customers are worried about the quality of SMT processed products when they choose SMT chip processing factories. They want to know how the manufacturers can ensure that the quality of processed products meets the requirements. The following is an introduction to the Dongguan […]
