Selective soldering is the process of selectively soldering components to printed circuit boards and molded modules that could be damaged by the heat of a reflow oven or wave soldering in a traditional surface-mount technology (SMT) or Through-hole technology assembly processes.This usually follows an SMT oven reflow process; parts to be selectively soldered are usually surrounded by parts that have been previously soldered in a surface-mount reflow process, and the selective-solder process must be sufficiently precise to avoid damaging them.
Universal automation line
A universal automation line is configured for the assembly of electronics and mechanical devices. The universal automation line includes universal cells or stations that can be programmed to perform a variety of automated assembly tasks such as glue dispensing, screw driving, pick and place, etc. The stations are interchangeable by different module design such as selective soldering, heat stacking, bottom lead trimming, bottom screwing and ultrasonic welding. Each station can also include an automated robot, which is also interchangeable, to perform different tasks and complete fully automated assemblies. The stations can be sequenced inline for a fully automated line or combined with some manual operation. The stations can communicate by standardized interfaces and local networks, and can be expanded to an intranet or the internet for remote control.
