Abstract

The invention discloses a device and a method for degumming in SMT (surface mounting technology) industry, which are used for removing a coating layer on a PCB (printed circuit board) board. The device comprises an optical system, a platform motion system, a CCD (charge coupled device) visual positioning system and a control system, wherein the optical system is used for performing the alignment transmission on CO2 (carbon dioxide) lasers and finally focusing on material surface and is used for walking along the laser track within the region through optical scanning; the control system is used for controlling the optical system, the platform motion system and the CCD visual positioning system; the platform motion system is used for performing the laser spanned degumming process through the matching motions of a numerical control platform along X and Y directions; the PCB board is arranged on the numerical control platform of the platform motion system; and the optical system is arranged above the numerical control platform of the platform motion system. By using the method and device provided by the invention, the defects of mechanical degumming, such as the influence of the mechanical degumming on the quality of the product, are avoided, the stress problem of the mechanical degumming is solved and the better degumming effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of degumming method, specifically, relate to a kind of laser degumming device and method thereof in SMT industry, it mainly utilizes CO 2 The laser removes the coating on the surface of the solder joints of the PCB. The so-called SMT is Surface Mount Technology (Surface Mount Technology) (abbreviation of Surface Mounted Technology), which is currently the most popular technology and process in the electronic assembly industry. Background technique [0002] Parylene on the surface of PCB solder joints is a new type of conformal coating material developed and applied by Union Carbide Company in the United States in the mid-1960s. It is a unique p-xylene polymer (Poly-P-xylylene poly Xylene) generic name for various models in the series. It can be used in electronics, electrical appliances, information, and communication products. It has the functions of acid and alkali resistance, rust resistance and...
