Understanding Precision Etching Processing Technology

To make a high-quality lead frame, it not only needs the precise calculation of the designer, but also needs a precise processing technology, that is - precision etching processing! Do you know the secret behind this technology?

Precision etching is a high-precision processing technology that is capable of engraving micron-level patterns and structures on metal films or photoresists. The unprotected parts are eroded by chemical reaction of ferric chloride chemicals to form the final desired pattern, and in the production of leadframes, this technology can realize extremely high precision and stability, so that the leadframes can maintain good electrical connectivity in extreme environments such as high temperature and high pressure.

In the precision etching process, you need to use a kind of material called "mask", it can protect the area does not need to etching, at the same time so that the etching solution can only act on the need to etch the area. The production of the mask also requires high-precision photolithography, which requires a set of perfect processing procedures and equipment to ensure the production of high-quality mask.

Precision etching processing is a high-precision, high-tech processing technology that can achieve micron-level processing accuracy, and currently realizes the etching thickness between 0.01mm-2mm, which provides important support for the development of the modern microelectronics industry.
