Overview of PCBA electrical stress test methods

Some basic testing and inspection tasks may be required to be performed on your PCB/PCBA during the manufacturing and assembly process, and it is recommended that these tests be performed, at the very least, to ensure continuity, accurate assembly, and si

Overview of PCBA electrical stress test methods

Quality control in mass production and prototyping has a common set of important tasks: the need for PCB testing. The specific set of tests you need to perform in a PCBA depends on its application area, desired service conditions, and, of course, the rele

PCBA manufacturers teach you to judge PCB quality

Debugging circuit board problemOne: measurement circuit board voltage method:Two: circuit board signal injection method:Three: circuit board mode method:Circuit board configuration needs to solve certain instruments for debugging, but also need long-term

How to solve the PCBA welding problem

When PCBA virtual welding occurs, we can solve the PCBA virtual welding from the following points: 1) judging the general fault range according to the fault phenomenon, 2) observing the appearance, focusing on the large components and components with larg

How to deal with PCBA processing correctly

In the choice of PCBA patch processing manufacturers, electronics factories are very careful, so we should choose from the following points: first, customer experience, second, production qualifications, three, cost, four, service

How to eliminate short circuit fault in PCBA processing

There are six points to evaluate the manufacturability of PCB design:1. DFM review of light board2. Check the consistency between the actual components and the pad3. Generate 3D graphics: heat, whether it is conducive to SMT reflow welding heat absorption

How does PCBA process solder paste printing

Solder paste printing is very important to PCBA in PCBA processing, which directly determines the overall welding effect of PCBA. In the process of PCBA processing, the printing effect of solder paste includes steel mesh, solder paste, printing process, d

PCBA processing requirements for plug-in hole design and the DIP plug-in processing process of the patch factory

The processing of plug-in components generally adopts wave soldering. Because the wave soldering time is very short, if the jack is connected to more ground/electric layers, the tin penetration will be poor, resulting in poor welding.

What do you need to know about PCBA's R&D and proofing?

When delivering the designed PCB file and BOM to the PCBA manufacturer, it needs to be analyzed from multiple perspectives to ensure that there is no delay in the project cycle to reduce the risk of product release.

Why is the price of small batch PCBA proofing expensive

This production line is equipped with solder paste printing machines imported from Sweden, wave soldering, X-RAY, and professional SMT processing technicians.

What are the operating rules of PCBA proofing?

In the series of articles analyzing the reasons for welding quality in the process of patch processing, we have made a certain analysis of the reasons for the voids caused by pcb coating in the process of patch processing.
