SMT is abbreviation of surface mount technology and is currently the most popular technology and process in the electronics assembly industry. Surface Mount Technology (SMT) is called surface mount or surface mount technology. It is a method of mounting a leadless or short lead surface mount component (SMC/SMD for short) on the surface of a Printed Circuit Board (PCB) or other substrate. Reflow soldering or dip soldering and other methods of solder assembly circuit assembly technology.
SMT processing
1.Single panel:
(1) Simultaneous solder paste placement and plug-in pads;
(2) Stick SMC/SMD;
(3) Insert TMC/TMD;
(4) Reflow soldering.
2. Double panel:
(1) Paste-reflow process, complete welding of double-sided chip components;
(2) Then apply solder paste on the through hole component pad on side B;
(3) Invert the PCB and insert the via hole component;
(4) Third reflow.
