Enterprises should pay attention to the circuit board proofing and proofing manufacturers of engineers and operators for good communication, and in the delivery of proofing materials when carefully check the relevant documents.
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.
High density and high speed will increase the radiation of the system, while low pressure and high sensitivity will reduce the immunity of the system. EMI is a threat to the safety, reliability and stability of electronic eq
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.
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...
PCB impedance refers to the resistance and reactance of the parameters, the alternating current plays an obstruction role. Impedance processing is essential in PCB circuit board production.
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.
Every accessory of the hot product is the vane of the quality of the hot product. Besides the quality of the accessories themselves, there is the matching and coordination problem of the accessories and other accessories in the use environment.
Only each module has good EMC and low EMI can ensure the realization of the whole system function.
