PCB Copper Plating Line

What are the characteristics of PCB ink? What is the role of FPC / PCB in the manufacturing process?
Oct. 27, 2021
The ink plays a role in protecting the copper foil in the production, so that the copper and will not be exposed, which will affect the subsequent processes. There are photosensitive ink, carbon ink and silver ink, and both carbon ink and silver ink have conductivity. The commonly used ink colors are white oil, green oil, black ink, blue ink, red ink and yellow ink.
Application of AOI in PCB manufacturing
Oct. 21, 2021
Although al technology has been widely used in AOI image processing, there are still huge application scenarios and space in the maintenance link. Especially today, with the rapid iteration of a algorithm, the future maintenance system will be an intelligent maintenance system integrating various al algorithms.Of course, these al algorithms can be simple regression and classification algorithms, as well as complex reinforcement learning and structured learning. Strong artificial intelligence and weak artificial intelligence are controversial philosophical issues today.
Why does PCB film clamping occur and how to improve it ？
Oct. 20, 2021
With the rapid development of PCB industry, PCB is gradually developing towards high-precision fine lines and small aperture. Generally, PCB manufacturers have the problem of electroplating film clamping. PCB film clamping will cause direct short circuit and affect the primary yield of PCB through AOI inspection. Serious film clamping or too many points can not be repaired, which will directly lead to scrapping.
Detailed explanation of three common drilling holes in PCB
Oct. 19, 2021
In PCB production process, drilling is very important and should not be careless. Because drilling is to drill the required through holes on the copper clad laminate to provide electrical connection and fix the functions of devices. If the operation is improper, there is a problem with the through-hole sequence, and the device cannot be fixed on the circuit board, which will affect the use at first, and the whole board will be scrapped at last. Therefore, the drilling process is very important.
Why poor development happens in PCB developing and how to solve it ?
Oct. 18, 2021
The so-called infiltration plating is that the plating solution is deepened due to the weak adhesion between the dry film and the surface of copper-clad foil, resulting in the thickening of the coating in the "negative phase" and the plated tin lead corrosion resistant layer, which brings problems to the etching. It is easy to scrap the printed circuit board, which is a key point to pay special attention to in production.The causes of infiltration during pattern electroplating are analyzed as follows
How does the PCB developing machine work and what is it made up ?
Oct. 13, 2021
Generally, the developing machine is composed of power system, developing solution tank and spray pipe, water rinsing tank, extrusion (water) roller, gluing tank, etc. a good PCB developing machine should also have timer and temperature control system.
