It is a welding method that the welding end face of the components and the PCB welding pad are coated with paste solder and assembled together, heated until the solder is melted, and then the welding area is cooled.
Aluminum is a very attractive material with abundant resources, low cost, excellent thermal conductivity and strength. In addition, it is very environmentally friendly and can be used on most metal substrates or metal cores. Due to the advantages of econo
found a short circuit phenomenon. Take a board to cut the line (especially suitable for single/double board), after cutting the line, each part of the function block is powered separately, and gradually eliminated.
In order to make the test as high as possible failure coverage, in the design stage must pay attention to the selection of components and PCB layout, unfortunately, the actual situation is not always the case, rush to market and nervous development often
A collection of examples of printed circuit boards (PCBS) from professional pcba proofing manufacturers
Challenge: Equipment is expected or required to maintain as uniform surface pressure as possible to improve the quality of processed products
Practice has proved that it is difficult to find each and every solder paste fouling only by sampling the printed circuit board samples. Only 100% inspection of all circuit boards can ensure greater inspection coverage, thus enabling statistical process c
HDI board technology is characterized by BuildingUpProcess, commonly used resin coated copper foil (RCC), or semi-cured epoxy glass cloth and copper foil lamination is difficult to reach fine lines.
Printed circuit boards are assembled electronic parts1. Printed circuit board (PCB)PCB is the abbreviation of Printed Circuit Board (Printed Circuit Board). Also known as printed circuit board, printed circuit board, because it is made by electronic print
How LED Printed Circuit Boards (PCBs) WorkAs the technology of the world continues to evolve, so does the technology in the field of LEDs, and LED Cases is a field that involves combining two technological approaches in order to come up with other methods
The medical field is one of the most sensitive applications requiring PCBS because it requires precision, reliability, and high quality components. For this reason, medical PCBS are specifically designed to suit specific environments, laboratories, and te
The lines form "copper roots" on both sides after etching, and the copper roots narrow the line spacing, resulting in printed circuit boards that do not meet the requirements of Party A, and may even be rejected.
PCB board test system will have a new design idea, the use of automatic test system based on USB bus and virtual instrument design idea, give full play to the role of the computer
