Release film in the hot press pressing process need to pay attention to what?
A hot press is a device that heats two pre-coated tin-coated parts to a temperature sufficient for the solder to melt and flow. After solidification, a permanent electro-mechanical connection is formed between the parts and the solder. Should be different products, heating rate can be selected. Titanium alloy head to ensure average temperature, rapid temperature rise and long service life. The head is specially designed to be horizontally adjustable to ensure that the components are pressurized evenly. Temperature control, clear and precise. Equipped with digital pressure gauge, pressure range can be preset.
Hot press in the production of pressing process using pulse heating principle, due to the special design of the welding head surface, welding surface resistance is very small, the current will pass through the least resistance section. By constantly changing the voltage, adjust the current level, through the welding head to make it quickly heating. Release film for hot press is very important, hot press release film in the production process, first to meet the high temperature characteristics, usually resistant to high temperature 200±5°C, in addition to no release of gas, there is no chip, no glue between layers, no vacuum system pollution, does not affect the surface quality of hot press circuit board. The release film produced by sesson desheng technology co., LTD., a supplier of adhesive release film, is cheaper and of better quality than the general release film on the market.
The above content hope to help you, saishengdecheng has a professional r & d sales team, is a professional engaged in FFC, FPC, adhesive, die-cutting and other consumables manufacturers, the production of products at a high price, favored by many dealers and manufacturers.
The company's main production equipment, all the equipment in the dust-free workshop, specializing in transparent release film, fluorine separation film, PET film, film, imported release film, auxiliary materials supporting production supply, the products are mainly used for line FFC, FPC, die-cutting and adhesive products. In order to ensure the quality of each product, the products are tested by imported instruments.
We in line with "by the sense of responsibility to do things, life with a grateful mind" of the enterprise vision, from the "focus on customer needs, the pursuit of customer satisfaction, quality to build brand, with services to win customers" business philosophy, and actively expand marketing channels, forge ahead, continuous innovation of our products and improve our service, make the company develop steadily with the customer together create a better future.
