How to avoid rework in PCB design
The role of PCB board is not only to combine scattered components, but also to ensure the regularity of circuit design, a good way to avoid the chaos and error caused by manual wiring and wiring.

What are the rules of industrial PCB circuit board maintenance?
Industrial circuit boards should pay attention to heat dissipation problems; The second is printed board copper foil line, poor quality circuit board power supply line copper foil is very thin, easy to burn due to the current.
What are the PCB routing rules and techniques?
In PCB design, wiring is an important step to complete the product design, it can be said that the previous preparation work is done for it. PCB routing includes single - sided routing, double - sided routing and multi - layer routing.
What are the tips for PCB wiring?
Almost all PCB design software includes a tool called an autocabler, but the autocabler never does the wiring for itself.
The importance of the first part detection in PCBA processing
The purpose of thawing back temperature: can make the flux and tin powder evenly distributed, so as to give full play to the various characteristics of tin paste; The viscosity and activity of the solder paste after refrigeration are different from that o
PCB board welding requirements in PCBA processing
PCBA processing and welding process requirements for PCB board: 1. Heat resistance, 2. PCB shape, 3. PCB size, 5. PCB process edge, 6. PCB reference identification point, 7. Plate design, 8, can withstand solvent washing
Specification for PCB storage and inspection in SMT factory
PCB inspection contents: ① appearance inspection: ② size measurement: ③ furnace temperature test: ④ pad welding force test: ⑤ Check the PCB board factory report
Influence of SMT material on welding quality of PCBA
When the welding ends or pins of components are oxidized or contaminated, welding defects such as poor wetting, virtual welding and voids will occur in reflow welding. Poor coplanar properties of components will also lead to welding defects such as virtua
How do PCBA processing plants select high quality reflow soldering?
The heating methods of reflow welding are generally divided into two categories: one is by the red lamp and adapted tube heater; The other type is ceramic plate, aluminum plate and stainless steel plate heater.
PCBA board aging test standards and methods
pcba aging test standards: 1, low temperature work, 2, high temperature work, 3, high temperature and high humidity work
PCBA cleaning techniques
Wave soldering process: Insert components into corresponding PCBA through holes → spray flux → preheat (temperature 90-110℃) → wave soldering (240-260℃) → cooling → repair welding → remove pins of excess components → check solder joints
PCBA processing and SMT processing difference
PCBA processing and SMT processing differenceThe whole process of PCBA processing actually includes SMT patch processing. SMT patch processing is only part of the PCBA process, which literally means a wider range of processes
