Assembled circuit board companies typically require a range of equipment to complete the entire manufacturing process, which includes, but is not limited to, the following categories:

Pre-processing Equipment: Including substrate coolers, cutters, punching machines, pouring machines, etc., which are used to perform the necessary pre-processing of the substrate in preparation for the subsequent manufacturing process.

Production Base Equipment:

Equipment for copper foil attachment, exposure, plating, etc.: Used for attaching copper foil to the substrate and forming circuit patterns through processes such as exposure and plating.

Semiconductor devices and vacuum exposure machines, needle detectors, etc.: play a key role in specific steps to ensure the smooth progress of the production process.

Coating Equipment: Such as shielding varnish sprayers, spray painting machines, thermal descaling machines, etc., which are used to apply protective layers such as soldermasks/inks to prevent contamination and abrasion on the surface of the circuit boards.

Multilayer and Flexible Circuit Board Production Equipment: Such as circuit diagram tanning machine, photolithography machine, polishing machine, etc. These equipment can effectively improve the production process, improve the quality and efficiency of product production.

Welding and Testing Equipment:

Welding Equipment: Such as wave soldering, reflow soldering, etc., used to connect the components with the circuit board.

Inspection Equipment: Such as automatic optical inspection instrument (AOI), solder paste detector (SPI), automatic X-ray inspection (AXI), etc., used for quality inspection and testing of circuit boards to ensure that the product meets the standards and requirements.

Mounting and Printing Equipment:

Mounter: Uused to accurately place components on circuit boards to automate the assembly process.

Printing Machines: Such as solder paste printing machines, used to print solder paste on circuit boards in preparation for subsequent soldering processes.

Other Auxiliary Equipment: Depending on the production needs, some auxiliary equipment may also be required, such as lapping machines, cleaning machines, etc., for the necessary treatment and cleaning of the circuit boards.

Inspection and Measurement Equipment:

Microscope: Used to check the microstructure of the circuit board to ensure the accuracy of components and circuit connections.

Impedance Tester: Used to measure the impedance value of circuit boards to evaluate their electrical performance.

Insulation Resistance Tester: To check the insulation performance of circuit boards to ensure the reliability of products in harsh environments.

Environment and Safety Equipment:

Constant Temperature and Humidity Room: Used to control the temperature and humidity of the production environment to ensure that the circuit boards are not affected by external conditions during the production process.

Exhaust Gas Treatment System: Used to treat the exhaust gas generated during the production process to reduce the pollution of the environment.

Safety Protection Facilities: Such as anti-static floors, guardrails, etc. to ensure the safety of operators.

Logistics and Warehousing Equipment:

Shelves and Warehousing Systems: For storing raw materials, semi-finished products and finished products to realize effective material management.

Logistics and Transportation Equipment: Such as forklifts, conveyor belts, etc., used for the transportation and flow of materials within the factory.

R&D and Test Equipment:

Circuit design and Simulation Software: Used for circuit board design, simulation and optimization to improve the accuracy and efficiency of product design.

Laboratory Equipment: Such as high-temperature aging chambers, hot and cold shock test chambers, etc., used to conduct reliability tests on circuit boards to ensure that they can work properly in a variety of extreme environments.

The configuration and use of these devices will directly affect the assembly circuit board company's production efficiency, product quality and market competitiveness. Therefore, the company needs to be based on their own actual situation and needs, rational planning of equipment configuration, and regular maintenance and upgrading of equipment to ensure the stability and reliability of the production process. At the same time, the company should also pay attention to industry dynamics and technological development, and actively introduce advanced equipment and technology to enhance its production capacity and technical level.
