1, SMT patch processing technicians wear the electrostatic ring that is OK, and check the electronic components of each order without errors/mixing, damage, deformation, scratches and other adverse phenomena before plug-in.2. The plug-in board of the circuit board needs to prepare the electronic materials in advance, and pay attention to the correct polarity direction of the capacitor.

High assembly density, small size and light weight of electronic products, the volume and weight of the patch components are only about 1/10 of the traditional plug-in components, generally after smt patch processing, the volume of electronic products is reduced by 40%-60%, and the weight is reduced by 60%-80%.

smt processing technicians are responsible for maintaining the placement machine, and some should be programmed to paste on the motherboard.smt is a surface assembly technology, which is a more popular technology and process in the electronic assembly industry. smt processing It is a kind of pin-free or short lead or ball array package of surface assembly components (referred to as SMC/SMD, Chinese called chip components) installed on the surface of the Printed Circuit Board (PCB) or other substrate surface, Circuit assembly by welding by reflow or dip welding.

The basic components of smt chip processing include: screen printing (or dispensing), mounting (curing), reflow welding, cleaning, testing, and repair.1, screen printing: its role is to solder paste or patch glue to the PCB solder pad, to prepare for the welding of components. The equipment used is a screen printing machine (screen printing machine), located at the front of the SMT production line.

smt patch processing is a series of process processes based on PCB. SMT is a surface assembly technology (surface mount technology), is currently a popular technology and process in the electronic assembly industry. smt chip processing refers to the short term of a series of process processes based on PCB, PCB is a printed circuit board
