With the rapid development of the electronics industry, PCB wiring is becoming more and more sophisticated. Most PCB manufacturers use dry film to complete the graphics transfer, and the use of dry film is becoming more and more popular. However, I still encounter many problems in the after-sales ...

The long and short golden finger encapsulation is designed to have a power-on timing difference when the PCB board is plugged and unplugged. For example, when the golden finger is removed, the short finger will cut off the power supply first to play a protective role. Generally, when the golden ... Read More

Printed circuit board (PCB) warpage and distortion are usually among the highest levels of misidentified failures because it may be the least understood. Imagining a completely flat rigid circuit board as a standard is a fallacy that many newcomers believe. Understanding the causes and causes of PCB ... Read More

When customers provide production materials to PCBA factory, they should prepare the following production materials list: 1. PCB Gerber file (a layered file that defines each layer of circuits, printed boards, screen printing, etc., used to make PCB bare boards) 2. BOM (Bill of Materials, that is, a ... Read More

In today's social development trend, the basic construction of ecological civilization and the management methods of ecological environmental protection have become more and more urgent. Because the ecological environment is immediately related to people's social reproduction, it is the future life ... Read More

HDI PCB (High Density Interconnect PCB) is a relatively high line distribution density of circuit boards using microblind and buried via technology. This is a process that includes inner and outer wires, and then uses holes and metallization in the holes to achieve the function of joining each inner ... Read More

When you encounter the problem of routing/short-circuiting of FPC flexible circuit boards, an effective method is to check under an optical microscope whether there is a line break. It can be seen that most of the route can penetrate electron-optical equipment, and only have encountered several ... Read More

Every electronic device has a rated life, but due to mechanical shock, thermal shock and vibration, premature failure may still occur. Thermal cycling is just a thermal simulation of vibration-repeated mechanical stress acts on the structure in the PCB, causing fatigue and failure. After repeated ... Read More

PCBA welding processing mainly refers to the production process of soldering PCB circuit boards and components through soldering process. Welding defects such as false welding are prone to occur during the welding process. Welding will seriously affect the reliability of the product and greatly ... Read More
