What is the HOTBAR?
1, popular explanation:
HOTBAR soldering, namely pulse is mainly used in LCD, PDP, mobile phone, etc. To welding of plastic or thin film pressure between two heating element, make the heating element into the strong current produce strong heat pulse in a very short time, then again give cooling, welding surface namely fusion under the heat pressure at this time.
2, Professional explanation: is the solder paste printing first on the printed circuit board (PCB), then use hot melt the solder and connect the conducting two needs to connect electronic components. Usually will soft board (FPC) welding on the PCB, so can achieve light, thin, short, small. It also can effectively reduce the cost, because can use 1 ~ 2 less soft board connector (FPC connector).
