Surface mounting technology (SMT) template manufacturing method

Abstract

The invention provides surface mounting technology (SMT) template air floatation cutting equipment. An SMT template manufacturing method comprises the steps that S1, preliminary positioning and fixingare carried out, specifically, an SMT template is placed onto a workpiece bearing assembly and clamped and fixed, an air floatation beam moves above the fixed SMT template, and identification pointson the SMT template are scanned and detected in sequence, and preliminary positioning and recording are carried out; S2, precise positioning and cutting are carried out, specifically, according to thepreliminary positioned and recorded position situation of the SMT template, the air floatation beam moves to the position of a graphic opening in the SMT template, and a cutting assembly is used forcutting corresponding graphic openings in the SMT template; and S3, precise positioning welding is carried out, specifically, welding pieces with different thicknesses of the SMT template are correspondingly put at the graphic openings cut in the step S2, and the cutting assembly is used for seamlessly welding the welding pieces to the cut graphic openings. According to the SMT template air floatation cutting equipment, the method of laser cutting and welding is adopted to manufacture the stepped template, the problem of environmental pollution is solved at a source, the precision requirementsof the template manufactured by the manufacturing method are far beyond the manufacturing capacity scope of conventional laser welding and laser cutting processes.

Description

technical field [0001] The invention belongs to the field of SMT, and in particular relates to a method for making an SMT template. Background technique [0002] Surface Mounting Technology (SMT for short) was born in the 1960s, and it plays a very important role in the development of the entire electronics industry. The step template (ie: a printing template with a thicker or thinner local position) ) As one of the SMT template product categories, with the needs of the overall technological progress of the industry, its demand is increasing. In the prior art, the stepped area on the SMT template is mostly made by etching or electroforming. However, etching or electroforming Electroforming will cause a lot of pollution to the environment due to the process itself, which is quite a headache for manufacturers. The problem of environmental pollution will greatly increase the cost of making steel plates, and at the same time the etching or electroforming process The complex pro...
