How to judge the quality of HDI printed circuit boards?

How to judge the quality of HDI circuit boards? ONESEINE, a manufacturer of HDI circuit boards in Shenzhen, has summarized some methods and will share them with you below.

High quality HDI circuit boards need to meet the following six requirements:

1. Check if the line width and distance of the HDI circuit board meet the requirements to avoid heating, open circuits, and short circuits.

2. High temperature, high humidity, and special environmental tolerance should be considered.

3. The copper surface is not easily oxidized.

4. No additional electromagnetic radiation.

5. The shape should have no deformation, and the hole position of the HDI circuit board and the deformation error between the circuit and the design should be within the allowable range.

6. High temperature copper sheet is not easy to peel off (all HDI circuit board products from Shenzhen ONESEINE Circuit will undergo IPQC inspection after each process is completed and qualified before proceeding to the next process)
