Lead frame manufacturers

Lead frame is a kind of used for integrated circuit chip carrier, and by means of bonding wire circuit inside the chip terminal ( Bonding point) Through with the electrical connection in the outer lead internal leads, and the electric circuits of the formation of the key components. In semiconductor lead frame mainly on solid chip, signal conduction, heat transfer effect, need to be in, bending strength, electrical conductivity, thermal conductivity, corrosion resistance, heat resistance, thermal matching, step by step, coplanar shape, stress release and so on to achieve high standards. The vast majority of semiconductor integrated block you need to use lead frame, is the important basic materials in electronic information industry. Lead frame according to the application in different semiconductor, can be divided into application in the integrated circuit lead frame and applied to discrete device of two kinds of lead frame. This semiconductor subsequent encapsulation mode adopted by the two categories each are not identical, phyletic and various. Different ways of packaging will require a different lead frame, therefore, usually in semiconductor encapsulation way to name the lead frame. Integrated circuit used widely and developed rapidly, currently has a DIP, SOP, QFP, BGA, CSP, and other packaging way; Discrete device is mainly all kinds of transistor, on most used TO encapsulate, SOT that two types of packaging. Lead frame classification list of China's lead frame industry today, there is still a gap compared with developed countries, with the domestic lead frame has been expanding its production enterprises, products production technology innovation, new technology advances, constantly, and will gradually replace the market share of domestic imports of lead frame. Dongguan precision electronics co. , LTD. Is a lead frame manufacturers, specializing in non-standard high-precision lead frame processing customized. Lead frame is widely used in connectors, relays, micro motors, audio products, IC encapsulation, automotive electronics, power supply, intelligent home appliances, intelligent wear, medical electronics, consumer is tasted industry such as power supply.
