The difference between leaded process and lead-free process of pcb

PCBA and SMT processing generally have two processes, one is a lead-free process and the other is a leaded process. Everyone knows that lead is harmful to humans. Therefore, the lead-free process meets the requirements of environmental protection, which is a general trend and an inevitable choice... Read More

Differences in characteristics between FPC and PCB

In fact, FPC is not only a flexible circuit board, but it is also an important design method of integrated circuit structure. This structure can be combined with other electronic product designs to build a variety of different applications. Therefore, from this point on Look, FPC and hard board a... Read More

The design points of the hard-soft fusion board of pcb circuit board

1. For power circuits that must be repeatedly bent, it is best to choose a single-sided soft structure, and choose RA copper to improve fatigue life.  2. It is proposed to maintain the inner electrical layer wiring of the bonding wire to bend along the vertical direction. But sometimes it cannot ... Read More

Five requirements for pcb imposition

In order to facilitate the production and manufacture, PCBpcb circuit board jigsaw generally must design the Mark point, V-groove, and processing edge.  PCB appearance design 1. The frame (clamping edge) of the PCB splicing method should adopt a closed-loop control design scheme to ensure that th... Read More

Is circuit board PCBA cleaning really important?

“Cleaning” is often ignored in the PCBA manufacturing process of circuit boards, and it is considered that cleaning is not a critical step. However, with the long-term use of the product on the client side, the problems caused by the ineffective cleaning in the early stage cause many ... Read More

Common methods of circuit board repair

1. Visual inspection method By observing whether there is a burnt place on the circuit board, whether there is a broken place in the copper coating, whether there is a peculiar smell on the circuit board, whether there is a bad soldering place, whether the interface, gold finger is moldy and blac...

How to effectively remove harmful substances and reduce environmental pollution is a major task facing my country&#... Read More

6 ways to check the quality of PCB design

Poorly designed printed circuit boards or PCBs will never meet the quality required for commercial production. The ability to judge the quality of PCB design is very important. Experience and knowledge of PCB design are required to conduct a complete design review. However, there are several ways... Read More

Planning PCB to reduce interference, just do these things

Anti-interference is a very important link in modern circuit design, which directly reflects the performance and reliability of the entire system. For PCB engineers, anti-interference design is the key and difficult point that everyone must master. The presence of interference in the PCB board In... Read More

How to understand the circuit board circuit diagram

How to understand the circuit board wiring diagram? First of all, let’s first understand the characteristics of the application circuit diagram: ① Most of the application circuits do not draw the internal circuit block diagram, which is not good for the recognition of the diagram, especiall...

Why should PCB be immersed in gold?

1. What is Immersion Gold? To put it simply, immersion gold is the use of chemical deposition to produce a metal coating on the surface of the circuit board through a chemical oxidation-reduction reaction.   2. Why do we need to immersion gold? The copper on the circuit board is mainly red c... Read More
