SMT Assembly Process 1. Place (curing) Its role is to melt the patch glue so that the surface mount components and the PCB board are firmly bonded together. The equipment used is a curing oven, located behind the placement machine in the SMT line. 2. Re-soldering Its role is to melt the solder paste, so that the surface mount components and the PCB board are firmly bonded together. The equipment used was a reflow oven, located behind the pads. Mounter on SMT production line. 3. SMT assembly cleaning What it does is remove solder residues such as ux The assembled PCB is harmful to human body. The equipment used is a washing machine, the location may be Not fixed, it may be online or offline. 4. SMT assembly inspection Its function is to check welding quality and assembly quality The assembled PCB board. The equipment used includes magnifying glass, microscope, in-circuit tester (ICT), needle tester, automatic optical inspection (AOI), X-RAY inspection system, functional tester, etc. 5. SMT assembly rework Its role is to rework the failed PCB board Fault. The tools used are soldering iron, rework station, etc. anywhere on the production line. As you know, there are some small issues during production, so hand rework assembly is the best way. 6.

The Difference Between FFC And FPC Line
FFC cable thickness is 0.12mm. FFC cable by the upper and lower insulating film, the intermediate laminated flat copper conductors, so the cable thickness on the film thickness + IT = + conductor thickness at film thickness. Commonly used film thickness: 0.043mm, 0.060,0.100, commonly used conductor thickness: 0.035,0.05,0.100mm the like;
Second, the prices are different due to different production processes. Different production processeses result in different costs. Such as gold-plated board and tin-plated board, the shape of the routing and punching, the use of silk screen lines and dry film lines will form different costs, resulting in price diversity. 2. The FPC line is a flexible printed circuit. From the manufacturing point of view, the circuit formation methods of the FPC line and the FFC line are different: (1) FPC is to process FCCL (flexible copper clad foil) by chemical etching to obtain flexible circuit boards with different circuit patterns; (2) The FFC cable uses a flat copper wire conductor sandwiched between the upper and lower layers of insulating foil films. 3, the main FFC cable specifications and special features: FFC cable life is generally 5000-8000 opening and closing times, if the average opening and closing 10 times a day, the whole working life will be a year and a half or so. Key Specifications / Special Features: Working temperature: 80C 105C. Rated voltage: 300V, this is suitable for general electronics, electrical appliances internal connections, such as audio-visual equipment, etc. Conductor: 32-16AWG (0.03-1.31mm2), tinned or bare copper stranding.
