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 should I choose the SMT plant
Circuit board as a high-end electronic industry essential products, its role in electronic products plays a pivotal role, so for the circuit board daily maintenance tools is more important, so how should we deal with the dust on the circuit board? Method
How can PCB design be optimized to meet lead-free requirements
At present, lead-free environmental protection is a technical challenge for PCB manufacturers and PCBA manufacturers. A lot of manpower and material resources have been spent on PCB design. The following progress has been made: 1. Improvement of the speci
How to judge the welding quality of BGA slices
Virtual welding is a very common line fault, one is in the process of circuit board production, caused by improper production technology, when the unstable state; The other is that after long-term use of electrical appliances, some of the more serious hea
How to solve the problem of substrate size change
Reasons for the change in the size of the substrate in the process of circuit board production: (1) the difference in the direction of longitude and latitude caused by the size changes of the substrate, the substrate surface copper foil is etched off the
How to improve the PCB short-circuit problem
PCB circuit opening and short circuit are problems encountered by PCB manufacturers almost every day, so pcb manufacturers should pay attention to production and avoid short circuit problems
How to solve the SMT patch processing tablet problem
PCBA manufacturers take you to solve the SMT patch processing tablet problem: In SMT patch processing, sometimes there will be the phenomenon of stellerization. The root cause of stellerization is that the welding tension on both sides of the component is
How do you judge the PCB board
How do we judge the quality of PCB board: 1. Distinguish the quality of PCB board by its appearance; 2. From the PCB board itself to judge its quality, 3. How to judge the SMT patch processing quality: 1. A complete, smooth, polished surface; 2. The appro
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 SMT patch processing solve solder spot problems
Solder joint stripping sometimes occurs in through-hole wave soldering. This phenomenon is caused by the failure between the solder joint and the welding pad. The main reason for this phenomenon is that the thermal expansion coefficient between the lead-f
