PCB Manufacturing Equipment
The PCB manufacturing equipment in the figure is used in the process of transferring the exposed pattern on the photoresist to the circuit board, and the unexposed photoresist is removed by the developer to expose the required circuit pattern. It includes developing tank, developing solution supply system and cleaning system etc.
It uses alkaline solution to remove unnecessary copper foil on the circuit board, alkaline etching equipment includes etching tank, etching tank moving system and control system.
The etching process is performed in a vacuum environment. By placing the circuit board in a vacuum chamber and introducing etching gas, the gas reacts with the material on the surface of the circuit board to achieve the etching effect. The purpose of configuring this kind of PCB timing equipment is to produce high-frequency circuit boards and other projects that require fine structure and high precision.
CNC, or Computer Numerical Control, is a through-hole PCB manufacturing used for automation.
A more traditional PCB depaneling equipment, which cuts or trims circuit boards through high-speed rotating cutting tools, and divides the entire circuit board from large substrates into single boards in mass production.
A more advanced board depaneling machine, which cuts and evaporates the material on the circuit board with a laser beam to achieve high-precision cutting lines or holes, providing quality assurance for high-demand PCB-Herstellung and assembly orders.
PCB Assembly Equipment
Solder paste printing machine and solder paste dispensing machine are easily confused concepts. The picture above shows a solder paste printing machine, which uses a printing scraper or printing roller to evenly press the solder paste on the surface of the circuit board with the pad position. The solder paste dispenser uses a dispensing needle or nozzle to control the flow and position of the solder paste to apply the solder paste to a specific area of the circuit board in a dispensing manner.
Connect different equipment of SMT production line for staged circuit board delivery.
Used as a post-assembly soldering process, Wellenlöten is typically found in through-hole assembly lines.
PCB Test Equipment
A device for detecting and analyzing the internal structure of an object, which penetrates the object through an X-ray beam and generates an image. In the PCBA field, X-Ray inspection can provide advantages such as defect detection, internal structure analysis and non-destructive testing.
As shown in the figure above, the AOI equipment is directly connected to the welding equipment, and experienced operators perform automatische optische Inspektion to help achieve efficient and accurate PCBA.
Also known as SPI detector, it is used to detect the printing quality of solder paste in SMT process. It scans the solder paste printing area through optical or laser technology to detect problems such as offset, short films, defects, missing or excess solder paste.
