PCB circuit board hole blocked, what is the reason?
As electronic products to "light, thin, short, small" direction of progress, PCB also to high density, high difficulty degree of progress.

What are the difficulties in the production process of PCB multilayer circuit board?
There are many exquisite PCB presets, whether it is the principle of presets or components mix and match, are strict requirements.
What is PCB multilayer board?
PCB multilayer board is the multi-layer line layer, between each two layers is the media layer, the media layer can do very thin.
Frontal temperature gun circuit board PCBA processing
When the infrared frontal temperature gun is aimed at and close to the distance between the measured object and the tube measured by the sensor, the infrared sensor plate will collect the temperature and convert it into an electrical signal.
How to distinguish HDI circuit board is several levels of blind buried?
The trend of printed boards in global shopping malls is to introduce blind buried hole circuit boards in high-density interconnected products, and then more useful space saving, so that the line width, line spacing is thinner and narrower.
Cause of the bubbling problem on the board
For different PCB manufacturer facilities technical level may reveal different causes of bubbling phenomenon, the specific situation should be analyzed in detail, can not be mentioned together.
Frequently asked Questions about purchasing circuit boards
In production, we will have the engineering review and approval of your information, if there is a problem the first time to combine with you! In order not to delay your time, the combination form you provide must be accurate.
What materials and classification do pcb circuit boards have?
Copper clad plate is the basic material of electronic industry, mainly used in the processing and manufacturing of printed circuit board (PCB), widely used in TV, radio, computer, computer, mobile phone, communication and other electronic products.
What are the problems affecting the quality of PCB copy board
in the process of PCB copying board, PCB scanning is undoubtedly the first step of all processes. Therefore, we first get a good PCB board, and then it must be scanned by the computer, and then backup the relevant parameters and the original PCB layout.
What is the relationship between chip decryption and PCB copy board?
PCB copy board and chip, the two are more like the relationship between the lips and teeth, think about it carefully, PCB copy board is like the shelter of the chip, without the shelter, the chip can only wander around, and can not play their role.
What is PCB board copy board?
Copy board is also called cloning or imitation, is a product design of PCB board reverse technology research, copy board is equal to copy board, copy the circuit board on the hand, and then mass production.
