This applies not only to the interconnection and isolation of circuit boards, but also to the high frequency testing of circuit boards, because the material will change its electrical characteristics after undergoing the component welding process.
That's all we have manufacturing capacity for, and when 5G starts in earnest, it will put pressure on those parts markets.
Factors that determine perfect wave soldering in PCBA processing include: 1. Stable complete contact; 2. heat
FPCS have many applications in a number of different fields. They are used in solar cells, mobile phones, vehicles and aircraft. Many of these applications require thin and durable flexible sheets, which can therefore withstand bending, folding or rolling
Methods for rapid maintenance of faults after PCBA processing: one, visual inspection method, two, resistance method, three, voltage method, four, waveform method, five, current method, six, component replacement method, seven, step by step investigation
pcba electronic products processing process: one, customer data file, two, document review, three, technical preparation, four, material purchase and arrival, five, material inspection and machine, six, start production, seven, test and delivery
What is PCB design: PCB design is based on the schematic diagram of the circuit to achieve the function required by the circuit designer. PCB design mainly refers to layout design, which needs to consider the layout of external connections. Optimized layo
PCB copy board use: The purpose of PCB copy board is to learn the latest foreign electronic circuit design technology, and then absorb the excellent design scheme, and then used to develop and design more excellent products
Copper coating on PCB board, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line backflow area, reduce the signal external electromagnetic interference
SMT patch proofing processing and installation IC notes: 1, the welding time is short, not more than 3s, 2, the use of electric iron constant temperature 230 degrees, 3, proofing table do anti-static treatment. 4, choose some pointed and narrow iron head,
he system speed can be greatly reduced because of the increase of delay time caused by the delay of 2ns per 30cm line length of the common interconnect on the baseboard. Image shift register synchronization counter.
with the increase of labor cost and raw material price again and again, many customers began to require product price reduction to save costs.
