The initial wiring phase uses a large 0.050 inch hole spacing in the SMD outlet and takes into account the type of package used. The subsequent wiring phase allows the holes to be positioned close to each other so that all tools achieve the highest spread
PCB customization, BOM, material selection and other electronic industry supply chain solutions, one-stop to meet the comprehensive needs of small and medium-sized customers in the electronics industry.
Some customers have designed contour lines for Keep layer, Board layer, Top over layer and so on, and these contour lines do not coincide, which makes it difficult for PCB manufacturers to judge which contour line shall prevail.
From the point of view of function, the hole can be divided into two categories: one is used as an electrical connection between the layers; The second is used for fixing or positioning devices. In terms of technological process, through holes are general
Copper coating on PCB, if the grounding problem is handled well, is "more advantages than disadvantages", it can reduce the signal line backflow area, reduce the signal external electromagnetic interference.
a large number of customized a bunch of non-standard cables, resulting in the production line of the cable versatility is very low, once a model inventory is used up, the relevant car type no cable available, the production line can only shut down and oth
The most basic is often the most difficult to break through, but in the face of 5G, PCB should break the bottleneck, resistance and tolerance components such as "small" is an inevitable trend.
In addition, there is still some room for operators to increase investment in 5G construction plans. Pay attention to communication equipment vendors and their suppliers.
All of these problems can cause the solder shield to detach from the circuit board and eventually lead to corrosion of the copper circuit. Poor insulation characteristics can cause short circuits due to unexpected electrical connectivity/arcing.
The PCB industry will benefit a lot in the industrial chain. With the emergence and rapid progress of 5G communication technology, a number of related fields are entering the situation of technology iteration and product application upgrade simultaneously
PCB copper wire falling off (also often said copper dumping) is bad, PCB factories are said to be the problem of laminate, requiring its production factory to bear bad losses.
As a result, future digital life situations such as remote teaching, intelligent diagnosis and treatment, and AI for industrial risk control have been started in advance.
