Low mold-opening costs, changes in molds of any shape, reducing design and development costs2. Achieve half-cut metal, add LOGO, brand production3. High precision, up to +/- 0.01mm, which can meet different precision requirements4. Products with complex shapes can also be produced in batches with quality and quantity5. No burrs and pressure points, the product does not deform and does not change the material properties6. Thick and thin materials can be processed in the same way to meet the production requirements of different IC lead frames7. Almost all metals can be etched, and there is no limit to various pattern designs8. Manufacture of various metal parts that cannot be completed by mechanical processingNetwork transactions, integrity is king!As the chip carrier, the IC lead frame is a key structural component that realizes the electrical connection between the terminal of the internal circuit of the chip and the external lead by means of bonding materials (gold wire, aluminum wire, copper wire) to form an electrical circuit The bridge role of the external wire connection requires the use of lead frames in most semiconductor integrated blocks, which is an important basic material in the electronic information industry. Product type includes TO, DIP, ZIP, SIP, SOP, SSOP, TSSOP, QFP (QFJ), SOD, SOT, etc. Mainly use precision die stamping method and chemical etching method for production.IC wire rack uses raw materials: KFC, C194, C7025, FeNi42, tamac-15, pmc-90, and so on. The selection of materials is mainly based on the desired properties of the product: strength, electrical conductivity and thermal conductivitycompany information NINGBO DonGSHENG INTEGRATED CIRCUIT ELEMENT CO.,LTD was founded in 1976, engaged in the etching industry for 32 years, mainly producing integrated circuit lead frame, hardware etching and other kinds of precision metal etching products, the products cover electronics, machinery, chemical, medical, military, aviation, aerospace, household appliances, sanitary ware, automobile and other industries and fields.Why choose ningbo dongsheng etching?1.Standard 17300m2 self-built factory with waste water treatment system2.Passed ISO9001, ISO14001 certification3.Has 8 experienced engineers and professional quality inspection team4.10 PCS OF etching machines5.Four etching lines6.Comprehensive inspection and quality inspection before shipmentOur goal is to provide one-stop manufacturing solutions to our valuable customers, saving their time and money.
