PCB color has no direct relationship with its performance, because the different color will not affect the performance of the circuit board. Black is the most prone to chromatic aberration, and the lines on black PCBS are difficult to read.
One of the many steps that can make a PCB design a success is choosing the right tools. While it may be possible that no single tool will meet all your needs, you must do some research beforehand and try to find the best product for your needs.
Car PCB occupies an important position. However, due to the special working environment, safety and high current requirements, the reliability of PCB, environmental adaptability and other requirements are high.
PCB circuit board four special plating methods: finger plating, through hole plating, coil continuous selection plating, brush plating.
Over-protection of the product can allow it to survive the harshest environmental conditions, but the "harshest environment" may be temporary or transient, so a resin solution with lower performance in the higher temperature range is usually suf...
Traditionally, we define PCB boards with more than 4 layers as "multilayer PCB boards", and more than 10 layers as "high multilayer PCB boards".
There will be engineering review and approval of your information, if there is a problem with the first time to combine with you! In order not to delay your time, the combination of the form must be accurate, if not combined, we will stop production!
It is easy to determine that the IC is damaged. These changes are not necessarily caused by the IC damage, nor do they necessarily indicate that the IC is good. Because some soft faults do not cause a change in DC voltage.
Width and spacing of printed wire are important design parameters, which affect not only the electrical performance and electromagnetic compatibility of PCB, but also the manufacturability and reliability of PCB.
Only each module has good EMC and low EMI can ensure the realization of the whole system function.
Because the wider the printed line is, the smaller the inductance is, the lead line from the pad to the hole should be widened as far as possible, and the width of the pad should be the same as far as possible. In this way, even the capacitance of 0402 pa
