PCB finished product inspection standards: the key to ensuring high quality and reliability
In the printed circuit board (PCB) industry, XDCPCBA has become a leader in the industry with its excellent manufacturing capabilities and comprehensive service range. As a leading PCB supplier, XDCPCBA not only has its own PCB factory, focusing on producing high-quality PCBs from 2 to 30 layers, but also demonstrates strong production capabilities and a deep understanding of diverse customer needs. In addition, XDCPCBA also provides free sample services for PCBs from 2 to 6 layers, which further demonstrates its emphasis on customer satisfaction.
However, advanced production capabilities and a diverse product range alone are not enough to ensure the quality of PCB circuit boards. In order to ensure that every PCB circuit board meets customer expectations and industry standards, XDCPCBA has developed a set of strict finished product inspection standards.
This set of inspection standards covers all aspects of PCB circuit boards, from appearance inspection to electrical performance testing to reliability and environmental adaptability assessment. In terms of appearance inspection, XDCPCBA's inspectors will carefully check the surface of the circuit board for scratches, stains, cracks or other defects. At the same time, they will also check whether the size and shape of the circuit board meet the design requirements, and whether the layout of the circuit and pad is reasonable.
In terms of electrical performance testing, XDCPCBA will use advanced testing equipment to test the key indicators of the circuit board such as conductivity, insulation resistance, and withstand voltage. These tests can ensure that the circuit board has good electrical performance under normal working conditions and can withstand certain electrical shocks.
In addition, XDCPCBA also pays great attention to the reliability and environmental adaptability evaluation of PCB circuit boards. They will simulate various harsh environmental conditions such as high temperature, low temperature, humidity, etc., and test the circuit board for a long time. These tests can ensure that the circuit board can still maintain a good working condition under various extreme conditions, thereby improving the reliability and service life of the product.
As a professional PCB and PCBA manufacturer, XDCPCBA not only provides high-quality PCB circuit board finished products, but also provides comprehensive PCB design, manufacturing and assembly services. These services cover multiple industries such as industrial automation, automotive electronics, communication equipment, Internet of Things, mechanical equipment, instrumentation, power equipment, medical equipment, aerospace, power supply appliances, household appliances and consumer electronics.
XDCPCBA's professional capabilities are not only reflected in its advanced production technology and equipment, but also in its deep understanding of customer needs and market trends. They are able to provide customized solutions based on the specific needs of customers, and continuously optimize products and services to meet market changes.
In general, XDCPCBA has established a good reputation in the PCB industry for its excellent manufacturing capabilities, comprehensive service range and strict finished product inspection standards. They are not only committed to providing customers with high-quality products and services, but also constantly innovating and forging ahead to promote the development and progress of the entire industry.
In the future, XDCPCBA will continue to uphold the concept of "quality first, unlimited innovation, customer first", continuously improve its own technical level and service quality, and provide more customers with high-quality PCB and PCBA solutions. At the same time, they will continue to pay attention to the development trends of the industry and changes in customer needs, and respond to market challenges and opportunities in a more flexible and efficient way.
As a leading supplier in the printed circuit board (PCB) industry, XDCPCBA's inspection standards cover multiple aspects to ensure the high quality of PCB circuit board finished products. The following are the main contents of the XDCPCBA inspection standards:
1. Appearance inspection
Circuit and pad: Check whether the circuit is clear and continuous, without breakage, short circuit or open circuit; the pad should be complete and flat, without missing, warping or pollution.
Surface quality: The surface of the circuit board should be smooth and flat, without scratches, stains, cracks, bubbles or peeling.
Size and shape: Check whether the size and shape of the circuit board meet the design requirements, and the edges should be neat and free of burrs.
2. Electrical performance test
Conductivity test: Use professional equipment to detect whether the circuits on the circuit board are conducting normally to ensure that there is no open circuit or short circuit.
Insulation resistance test: Measure the insulation resistance between the layers of the circuit board to ensure that it meets the specified value to prevent electrical breakdown.
Withstand voltage test: Apply a certain high voltage to the circuit board to check whether it can withstand the specified voltage without breakdown or damage.
3. Reliability test
Thermal shock test: Place the circuit board in a high temperature and low temperature environment alternately to check its thermal stability and whether there is deformation, cracking, etc.
Wet heat test: Place the circuit board in a high temperature and high humidity environment to check its moisture resistance, moisture resistance, corrosion, oxidation and other phenomena.
Vibration and shock test: Simulate the vibration and shock during transportation and use to check the firmness and stability of the circuit board.
IV. Environmental adaptability assessment
Salt spray test: Simulate the marine environment to check the circuit board's resistance to salt spray corrosion.
Mold test: Check whether the circuit board is susceptible to mold erosion in a humid environment.
Gas corrosion test: Simulate certain specific gas environments to check the corrosion resistance of the circuit board.
V. Other tests
Solderability test: Check the solderability of the pad to ensure that the solder can be evenly attached to the pad during the welding process.
Solder mask test: Check the integrity and adhesion of the solder mask to prevent the solder from penetrating into areas that should not be welded during the welding process.
Logo and text inspection: Check whether the logo and text on the circuit board are clear and accurate and meet the design requirements.
In summary, XDCPCBA's inspection standards cover appearance, electrical performance, reliability, environmental adaptability and many other aspects to ensure the high quality of PCB finished products. These strict inspection standards not only reflect XDCPCBA's emphasis on product quality, but also provide a strong guarantee for its leading position in the PCB industry.
