What are the advantages of PCBA contract processing?
PCBA contract material processing advantages: one, PCB, two, small order, three, shorter PCBA processing cycle, four, supplier responsibility is more clear, five, client to manufacturing end seamless link, six, very suitable for small enterprises
PCBA welding processing requirements for PCB board
In order to ensure the smooth completion of the special process and facilitate the PCBA welding process, PCB board must meet the manufacturability requirements in dimensions, pad distance and other aspects
PCBA processing function test process analysis
PCBA machining functional test process: 1. Functional test plan, 2. Test points, 3. System programming, 4. Test fixture
Influence of SMT lead-free processing on PCBA repair
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
The importance of manual welding line in PCBA processing
What is the warm-up to PCBA welding: When technicians and practitioners hear the words "temperature curve" or "temperature curve", they think of smt reflow soldering. Along the vast length of the weld zone, it is easy to see the four m...

What are the advantages of PCBA processing
The advantages of PCBA processing are: 1. Mass PCBA processing and assembly - complete equipment, 2. Our source of PCBA quality assurance, 3. Low cost PCBA one-stop supply chain management, 4. PCBA expert team
PCBA factories commonly use methods to identify counterfeit components
Test methods that can be used to identify counterfeit electronic parts in routine operations: first, visual inspection, second, electrical testing, third, X-ray inspection, fourth, XRF technology
What matters should be paid attention to during PCBA processing?
When PCBA is processed in the furnace: Because the pin of the plug-in element is scour by tin flow, some plug-in elements will be tilted after welding in the furnace, resulting in the element body beyond the screen frame, so it is required to repair weldi
