Description And Reasons of Poor Plating During Electroplating

Description And Reasons of Poor Plating During PCB Electroplating: 1. Pinhole. The pinholes are due to the hydrogen adsorbed on the surface of the plated parts, and they are not released for a long time. Make the plating solution unable to wet the surface of the plated parts, so that the plating layer cannot be […]

Process Technology for Improving the Quality of Multilayer Board Laminating

Due to the rapid development of electronic technology, the continuous development of printed circuit technology has been promoted. PCB boards have developed through single-sided-double-sided and multi-layered boards, and the proportion of multi-layer boards has been increasing year by year. The performance of the multi-layer board is developing to the extremes of high precision dense fine […]

Professional PCB Multilayer Board Pressing Process Description

Professional PCB Multilayer Board Pressing Process Description 1. Autoclave It is a container filled with high-temperature saturated water vapor and high pressure can be applied. The laminated substrate sample can be placed in it for a period of time to force moisture into the board, and then take out the sample again. Place it on […]

Solder Mask Process in the PCB Board Production Process: Repairing Board

The following is the third operation procedure of solder mask process in the PCB board production process: repairing the board. Repairing the board includes two aspects, to repair the defects of the image, and to remove the defects that are not related to the required image. In the process of repairing, you should pay attention […]

Solder Mask Process in the PCB Board Production Process: Developing

The second solder mask process in the PCB board production process is developing. The developing operation is generally carried out in the developing machine, and the developing parameters such as the temperature of the developing solution, the conveying speed, and the spray pressure are well controlled to obtain a better developing effect. The development is […]

Solder Mask Process in the PCB Board Production Process: Exposure

In the printed circuit board, the solder mask process is a printed board with solder mask after screen printing. Cover the pads on the printed board with a photo master so that it will not be exposed to ultraviolet light during exposure, and the solder resist protection layer is more firmly attached to the printed […]

Analysis and Discussion of Common Problems in Pre-Processing of PCB Silkscreen

Analysis and discussion of common problems in the pre-processing of PCB screen printing: (1) Dotted oxidation on the copper surface There are oxidation spots on the copper surface, which can cause the solder mask to fall off during hot air leveling. Generally, after the printed board is delivered for use, the lines with oxidation spots […]

Process and Precautions for Silkscreen Pretreatment

According to the company’s own conditions, a large number of experiments have been carried out on the pre-treatment process, parameters and matters that should be noted in the operation, and the process and parameters have been optimized, which has achieved good results. Process flow of pre-treatment: Due to the chemical cleaning and nylon brush processing […]

Factors Affecting Appearance of PCB: Pre-Processing for Silkscreen

With the rapid development of printed circuit board manufacturing technology, users now not only have higher and higher requirements for the internal quality of printed boards (internal quality refers to hole resistance, copper foil thickness, continuity test, solderability, etc.), but also the appearance of the printed board puts forward higher requirements, such as: the ink […]
