So what are the factors that affect the price of a PCB board? 1, PCB material difference, 2, surface treatment process difference, 3, PCB itself difficulty difference, 4, copper foil thickness difference, 5, customer quality acceptance standard difference
Traditionally, we define PCB boards with more than 4 layers as "multilayer PCB boards", and more than 10 layers as "high multilayer PCB boards".
To provide you with effective skills to improve PCB design spread rate and design efficiency: 1, determine the number of PCB layers, 2, design rules and restrictions, 3, component layout, 4, fan out design, 5, manual wiring and key signal processing, 6, a
Image of local separation caused by local expansion between layers of substrate or between substrate and conductive foil or between substrate and protective coating.
Advantages and applications of Anisotropic conductive adhesive (ACA) compared with traditional tin-lead solder: (1) It is suitable for ultra-fine spacing (50um), which is conducive to further miniaturization of packaging. (2) ACA has low curing temperatur
ISO9001 certification, CCC certification is the basic certification of PCBA manufacturers, can obtain ISO13485, IATF16949, UL certification of PCBA manufacturers are more comprehensive strength of the enterprise.
The battery of electric car can be said to be the most important, but many people do not care about it, but will complain about their electric car battery is not good, and the main reason is because of improper maintenance skills, resulting in premature b
thermoelectric separation copper substrate, multilayer industrial circuit board, power pcb board, medical circuit board, security PCB board, communication PC board, automotive circuit board, Instrument circuit board, military circuit board, composite bus
Now, various activity trackers, such as fitness bands and smartwatches, can also measure heart rate and other biological indicators or monitor sleep quality. Many people are excited about the new opportunity to track their fitness levels, giving rise to t
Circuit boards must use the thinnest coating material to provide maximum protection in order to minimize heat retention, additional weight gain and various other problems.
Common rules of thumb, vertical wiring, heat dissipation hole, right Angle wiring, "3W" rule, "20H" rule are used in PCB wiring.
SMT patch proofing and mounting on the space the size of the pinky finger means higher reliability and mounting accuracy, and two great progress can be summarized: first, the number of chip welding pins is reduced, and second, the welding volume is smalle
