How to solder the fpc connector

FPC (Flexible Printed Circuit board translated into Chinese is: flexible printed circuit board, commonly known as a PCB made of soft material (a material that can be folded and bent)) connector for LCD display to drive circuit (PCB) connection Currently, it is mainly based on 0.5mm pitch products.

The 0.3mm pitch product has also been used in large quantities. With the recent trend of LCD drivers being integrated into LCD devices, the number of pins of FPCs has been correspondingly reduced, and related products have appeared on the market. In the longer term, FPC connectors will be expected to be integrated with other mobile phone components on the frame of mobile phones or their LCD modules.

Products are mainly used in various digital communication products, portable electronic products, computer peripherals, measuring instruments, automotive electronics and other fields, such as mobile phones, digital cameras, notebook computers, MID, MP3\4\5, handheld game consoles, audio systems, etc. .

FPC connector, contact 3mm printed circuit board mounting height, lower, flip lock (one-touch rotary system), prevent detachment and FPC diagonal mating, elastic pin design, available in zero intermediate frequency and non-ZIF, available at 0.3, The 0.5, 1.0, and 1.25mm midline are available in tin-lead or lead-free surface mounts, with four holes, vertical and right angles available for stack top or bottom contact.

The principle of pulse DC hot welding machine, the principle of precision pulse heating power supply

1. The pulse power supply heating method is a method of heating and welding by using Joule heat generated when a pulse current flows through a high-resistance material such as molybdenum or titanium. Generally, a hot spot couple is connected to the front end of the heating nozzle, and the generated electric power is fed back to the control power source in real time to ensure the correctness of the set temperature.

2. The pulse current heating device is an instant heating method, and is energized and heated only when it is required to melt the solder.

3. The metal soldering tip melts the solder after it has passed through the current. After the solder melts, the power is turned off and cooling is performed. In the pressurized state until the solder solidifies, it is possible to obtain a highly reliable solder which is not soldered or floated.
