Laser marking technology, as a modern precision machining method, has unparalleled advantages compared with traditional machining methods such as machine labeling, manual labeling, inkjet coding and printing.
the industry of hot air reflow welding technology generally relies on two technologies: furnace temperature tester and real-time monitoring system.
Intercept the defective devices before welding to avoid the increase of maintenance cost and scrap risk after the defective mounting devices enter reflow welding.
Immediately afterwards, everyone, including myself, would get new phones so that we could have access to this new, wonderful technology.
There are several repair methods that are specific to the purpose of assembly, cost, and complexity of the solder mask required to be repaired.
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
Pad can be divided into 7 categories, according to the shape of the distinction is as follows: 1. Square pad,2. Round pad,3. Island pad,4. Teardrop pad,5. Polygon pad,6. Oval pad,7. Open pad
PCB board selection of lead-free spray tin and lead spray tin difference: 1, lead-free spray tin belongs to environmental protection process, does not contain harmful substances "lead", the melting point is about 218 degrees; 2, lead spray tin d...
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 machining functional test process: 1. Functional test plan, 2. Test points, 3. System programming, 4. Test fixture
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
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...
