Temperature zone equipment mass production suitable for mass production of PCB board placed on the walkway, to sequence through a number of fixed temperature zones, temperature zone too little will exist temperature jump phenomenon, not suitable for high-
In the electronics manufacturing industry, SMT (surface mount technology) is a very common process that allows the manufacture of electronic devices to become faster and more accurate. In the SMT processing process, there are many key processes that need
Strong maintenance ability and perfect after-sales service Experienced maintenance engineers can repair all kinds of patch welding caused by bad products, to ensure the connection rate of each piece of circuit board.
The calculation of SMT chip processing points is the main basis for the calculation of processing costs. Many customers who have only come into contact with the SMT processing industry do not know how to calculate the price.
Take the chip element with square pad design as an example, as shown in Figure 2 below. After the solder paste printing, if there is more solder paste, it is easy to produce tin beads.
Formation mechanism: During reflow welding, the heating of chip components is heated at the same time. Generally speaking, the pad with the largest exposed area is first heated to a temperature above the melting point of the paste. In this way, one end of
Another term we should avoid is touch-up. In this industry, many employees consider repair welding to be a normal and acceptable part of the assembly process. This is unfortunate, as rework and repair of any kind should be considered undesirable.
SMT patch processing technology popularity: A, electronic products small size, high assembly density. Two, high reliability, strong vibration resistance. Three, high frequency characteristics, reliable performance. Fourth, improve productivity and realize
Quality control is very important for patch plug-in processing. Only through effective quality control can we ensure the processing quality of patch plug-in, so as to obtain the best processing effect
SMT processing materials on the PCBA welding quality of the impact of the following: 1, the impact of components, 2, PCB, 3, the impact of solder paste
PCBA processing and SMT processing differenceThe whole process of PCBA processing actually includes SMT patch processing. SMT patch processing is only part of the PCBA process, which literally means a wider range of processes
The following are four ways to ensure the quality of PCBA processing: 1. Quality control, 2. Inspection and testing, 3. Use high quality raw materials: 4. Professional technical team
