We need a lot of production documents before the production of PCB, including BOM list. BOM list contains the number of materials needed for production, it’s the unique management document during production and PCB assembly​, which ensures the assembly sequence when it comes to actual processing. In the electronic assembly plant, BOM should be confirmed before production according to customers’ orders.

HDI PCB , full name is High Density Interconnection Technology Prited Circuit Board . It’s a technology of using mini blind and burried hole , a relatively high density distribution circuit board. HDI is designed for small capacity users of compact products .

With diversified layout requirement, Many different kind of PCB design softwares are chosed by electronics engineers, Here you can find brief introduction and recommendation for PCB design software list from our experienced engineer team. You can have a comparison based on the introduction.

With the rapid development of electronics technology, Printed circuit boards have been widely used in all kinds of fields to satisfy more products requirements

Aluminum plate production, direct drive cooling products in the industry application of rapid development, because of the characteristic of the aluminum plate with good heat dissipation,

get a PCB, first recorded on paper all the good vitality of the model parameters, and the location, especially the direction of the diode, three machine direction of the tube, IC notch. Preferably with a digital camera to shoot two photos vitality location.

Any electronic project even if properly designed and built with utmost care is prone to bug and issues. It is very crucial to test the product or PCB thoroughly in early stages of design to ensure your projects going well.

Planning the multilayer PCB stackup configuration is one of the most important aspects in achieving the best possible performance of a product. A poorly designed substrate, with inappropriately selected materials, can degrade the electrical performance of signal transmission increasing emissions and crosstalk and can also make the product more susceptible to external noise.

Accompany the consumer electronic products developing, people are pursuing for more small and clever products for easy carrying.This cause the engineer must use more small PCB size to finish the product design, so Multi layer HDI PCB board will be a trend for future

PCB practitioners have been very familiar with the phenomenon of this kind of price change of the circuit board But the prices of PCB tend to make buyers very confused, when a lot of people order online, they will question the prices of PCB.We can analyze the reasons for the price change from seven aspects.

All most people say that : i don’t want my PCB board to be damaged by water , but how could i do ? Don’t warry that , conformal coating would help you a lot .
