Product Description 



Professional Surface Mount Technology Assembly Line


Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to

temporarily attach one or several electrical components to their contact pads, after which the entire assembly 
is subjected to controlled heat, which melts the solder, permanently connecting the joint. Shenzhen Sunsoar Circuit factory,

established in 2008, is a high-end PCB&PCBA manufacturer in PCB and components assembly fields.."



Best PCB Wave Soldering Service From Sunsoar Circuit

" PCB Wave soldering is a bulk soldering process used in the manufacture of printed circuit boards. The circuit board is

passed over a pan of molten solder in which a pump produces an upwelling of solder that looks like a standing wave.

Shenzhen Sunsoar Circuit Factory has own pcb wave soldering lines and manual DIP soldering lines, it can meet the

different customer’s needs."
