Original new SMT SIPLACE TX module control board for placement machine

ASM mount is a closed working principle. If the quality of the board on the mounter is unstable, As a result, the working head of the mounter cannot return to the reference point, so there is no way to normal production. The equipment can work normally only if the board quality problem is found and repaired at the first time.

Surface-mount technology (SMT) is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). ... An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all.

An electrical component mounted in this manner is referred to as a surface-mount device (SMD). In industry, this approach has largely replaced the through-hole technology construction method of fitting components, in large part because SMT allows for increased manufacturing automation which reduces cost and improves quality. It also allows for more components to fit on a given area of substrate. Both technologies can be used on the same board, with the through-hole technology often used for components not suitable for surface mounting such as large transformers and heat-sinked power semiconductors.

An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix of solder balls (BGAs), or terminations on the body of the component.

PCB, also known as printed circuit board, is an important electronic component, the support of electronic components and the carrier of electrical connection of electronic components. Because it is made by electronic printing, it is called "printed" circuit board.
