PCB screen printing is an important process in PCB production, and it also determines the quality of the finished PCB board. So, what are the screen printing specifications and requirements for PCB circuit boards? 1. All components, mounting holes and positioning holes have corresponding silk screen labels. In order to facilitate the installation of the…
Double sided circuit board terminals block refers to the terminal block applied to the electrical connection of the programming circuit boards and is an electronic accessory product used for electrical connection. The mini PCB board terminals are classified into plug-in terminals, screw terminals, spring terminals, and fence terminals. 1. Plug-in terminal block Pluggable terminal block products…
PCB is the basic component of electronic products, and any electronic product needs to make through a hole PCB. Then, in electronic products, the PCB must be connected with other devices, which is the PCB interconnection. Generally speaking, there are three aspects of Printed Circuit Boards Connection: chip to PCB, inside PCB, PCB, and external…
The PCB screen printing layer of the circuit board is the text layer. Its function is to facilitate the installation and maintenance of the circuit and print the required logo patterns and text codes on the upper and lower surfaces of the high-density PCB, such as component labels and nominal values, component shapes and manufacturer…
In the process of using the PCBA board, it is inevitable to encounter harsh environmental conditions such as dust, salt spray, and high and low temperatures, so in order to protect the printed circuit, can anti-electrical glue be used? The resin is synthesized by a special formula and is an electric anti-glue. It is a…
What is the difference between double-sided, single-sided, and multi-layer circuit boards (PCBs)? Which one should be used for which application? What is a double-sided PCB board? Double-sided boards have wires on both sides, but if wires are to be used on both sides, there must be a proper circuit connection between them. The “bridges” between…
The damage caused by the short circuit of the PCBA can be quite large, from the burning of the component to the discarding of the oversized PCBA. At the same time, short circuit is also the most common fault of the circuit board. So, how to check and prevent short circuit of the PCB circuit…

In the process of SMT patching, some common faults will inevitably occur, resulting in poor PCBA. So, what are the common faults and solutions for SMT chip processing? 1. Component displacement: After the patch glue is cured, the components are displaced. In severe cases, the component pins are not on the pads. The Reasons: The…
Wave soldering Process is a batch soldering process used to manufacture PCBs. The basic equipment used in the process is the conveyor that moves the PCB through the different areas, the solder pan used during the soldering process, the pump that creates the actual waves, the sprayer for the flux, and the preheat pad. Solder…
