This paper introduces the inspection requirements of PCBA processed products: 1. Inspection requirements of PCBA processed products; 2. Quality requirements of component mounting process; 3
Shenzhen kingford is a PCBA processing manufacturer with more than 20 years of experience in PCBA processing. We have our own SMT processing plant, which can undertake mass SMT SMT processing services. Next, we will introduce what problems need to be cons
Core and key points of SMT process: The goal of SMT process is to produce qualified solder joints. A good solder joint depends on the right pad design, the right amount of solder paste and the right reflow temperature curve
5 suggestions to solve the problem of component shortage: 1. Expand the breadth and depth of cooperation between component suppliers; 2. Order to be prepared in advance, 3. Manage priority, 4. Reduce component loss, 5. Respect suppliers
Low cost is an important determinant in choosing a manufacturer, but it needs to be remembered that low cost should not come at the expense of quality, so the cost offered by the manufacturer needs to be competitive because the manufacturer has a strong r
Before SMT proofing, PCB should test: 1. PCB light plate deformation, surface smooth; 2. 2. Whether there is oxidation on the circuit board welding plate; 3. Whether the copper coating on the circuit board is exposed; 4. Whether the PCB has been baked for
PCBA circuit board debugging steps and methods: 1. Board surface observation and resistance inspection, 2. Install components, 3. Detect the output voltage of the power supply, 4. Preset overcurrent protection current, 5. Install other modules and power t
Accurate and reliable rework is more difficult in lead-free environments because the PCBA and the component closest to the component to be serviced must withstand multiple high temperature cycles. To protect the stability of the board, the preheating temp
Here are some possible reasons for potential growth: 1. PCB solder resistance details; 2. Surface treatment; 3. Screen printing; 4. Impedance details: 5
Common causes of material loss in SMT patch processing: 1, human factors, 2, machine factors, 3, material reasons, 4, working methods, 5, production environment
What is PCB, SMT, PCBA: 1, PCB is used to support electronic components, and provide lines, so that electronic components can form a complete circuit, 2, SMT is a popular technology, also known as surface mounting technology, 3, PCBA refers to the purchas
Classification of PCBA inspection items: inspection items are divided into four categories: material inspection, process inspection, identification inspection and quality consistency inspection
