How to use SMT solder paste to clean the solder spot first, pay attention to wipe very clean, do not have any residue, otherwise it will affect the next work, the solder paste opening time as short as possible, in the process of use, roughly estimate the
SMT Patch processing how to quickly ship What you needFirst, prepare SMT patch processing data in advance. Second, the SMD materials provided must be accurate
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
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
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
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
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
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
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 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
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
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
