The application and explanation of the release film of the soft and hard board

What is a soft and hard access board?

The birth and development of rigid boards composed of PPC circuit boards and PCB circuit boards have produced new flexible flexible board products.

Therefore, flexible cards are flexible printed circuit boards and hard wires.

Printed circuit boards with FPC and PCB characteristics are formed by pressing and other procedures, and are combined according to corresponding technical requirements.

Triple separation membrane: A series of separation sorting membranes are designed by Prisine Polterial Matterial Ltd., which are hard, soft and flexible printed circuit boards.

The upper and lower layers of the three-to-one separation membrane are high-temperature separation membranes, while the middle layer is a composite buffer membrane manufactured by exclusive technology and subject to strict quality control. It has high temperature strength characteristics, good filling coverage and good release effect, and is widely used in printed circuit boards with high filling coverage.

Benefits: 1. The separation film is used to separate production panels at high temperatures, and the cushioning material has effective filling and reflow effects, and effective compression and bonding effects on multilayer boards, as well as flexible bonding with relative thickness plate.

2. Triangular products will be fixed to the four corners to effectively prevent this kind of pressure and sliding problems. At the same time, this also saves a lot of labor (compared to a transaction, the transaction time is 2/3).

3. Smooth and smooth, effective filling, excellent covering performance, concise and simple operation

4. This procedure is clean and free from contamination, which is in line with the EU's recent requirements for ROHS requirements.

Features: According to customer pressure and license plate requirements, buffer: (100Um-150U-200U-300) + / 30um].

The deposited film: (25-36 Um-50 Um) + / 5-Transparent film or film is selected according to the requirements of the press and board. Film length: client specification length: + /-5MM film width: client specification Width width: +/- 5mm.

Packaging and storage: The packaging specifications of the product are various, and it can also be cut into an anion and a coil. Keep clean and clean warehouses below 45 degrees.

It should not be near fire, heat or direct sunlight. The storage period is 18 months from the date of export from the factory.
