In the mass production factory, there is no way for you to use an electric meter to slowly measure the correct Circuit of every resistor, capacitor, inductance and even IC on each board. Therefore, the so-called ICT(in-circuit-test) automatic Test machine
The layout of PCB circuit board is critical to the appearance and performance of the entire circuit board. Only part of the power filter and decoupling capacitors are shown in the schematic, but it is not specified where they are connected.
Different PCB boards have different pads, they all have different roles, in some ways is indispensable.
pcb board quick proofing is generally charged according to the information provided by customers and process requirements. For example: the number of boards, process requirements, ink color, board thickness, difficulty, expediting time and so on, a compre
the process of resin plug hole has been used more and more widely in the PCB industry, especially in some high layer, the board thickness of the product is favored. It was hoped that the use of resin plug holes would solve a range of problems that could n
The appearance of poor tin pcb is generally related to the cleanliness of PCB empty board surface. If there is no pollution, there will be no poor tin. Second, the solder itself is poor, temperature and so on.

A typical manufacturer can only request it twice per production cycle, and only check it once every few months. IR testing in simulated batches also prevents more spills of defective products, which are a prerequisite for quality PCB factories. In additio
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.
PCB board is composed of copper foil, resin, glass fiber cloth and other materials. There are differences between the physical and chemical properties of various materials. In the process of processing, it will go through chemical drops, cold and thermal
The technical realization process of PCB copying board is simple. Firstly, the circuit board of the copying board shall be scanned, the location of components shall be recorded, the components shall be removed and made into material list, and the material
The life and performance of circuit board machining depend on the selection of PCB board. Fiberglass FR4 is the most common material used for PCB substrates. For flexible PCBS, use Clapton or equivalent plastic. PCBS made from cheaper materials such as ep
