Technical Field

The invention relates to the field of machining, in particular to an automatic chip feeding device for circuit board welding.

Background

In recent years, in the development process of electronic industry, a trend of reflow soldering is very obvious. In principle, conventional cartridges may also be subjected to a reflow process, known as through-hole reflow soldering. Its advantage is that it is possible to complete all welding points in the same time, minimizing production costs. Temperature sensitive components, however, limit the application of reflow soldering, whether it be a cartridge or an smd. Selective soldering may be employed after reflow soldering in most applications. This will become an economical and efficient method of soldering the remaining cartridge and will be fully compatible with future lead-free soldering, and the chip, also known as a microcircuit, microchip, integrated circuit, refers to a silicon chip containing an integrated circuit that is small in size and is often part of a computer or other electronic device.
