Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board carriers, specifically to an aluminum alloy magnetic SMT carrier structure. Background Technology
[0002] With the development of electronic products, they are becoming lighter, thinner, and more highly integrated. The thickness of PCBs is getting thinner and thinner, ranging from 0.8mm, 0.6mm, 0.4mm, to 0.2mm, and FPCBs are even thinner, at 0.1mm or 0.075mm. The packaging of components is also getting smaller and smaller. Therefore, the requirements for the mounting technology of ultra-thin circuit boards are becoming more and more demanding.
[0003] Because ultra-thin circuit boards or FPCs cannot be directly processed on SMT equipment during mounting, a tray is needed first to attach the FPC or ultra-thin PCB to the tray, facilitating component mounting and processing on the SMT equipment. Most existing FPC trays involve attaching a layer of micro-adhesive silicone material to a rigid steel plate or other rigid board, then attaching the FPC to the silicone material, making the rigid board material the rigid base tray for the FPC. In an improved technology, on July 18, 2016, the applicant, Suzhou Markliheng Intelligent Technology Co., Ltd., designed "A Flexible Circuit Board Carrier for SMT," which uses the principle of magnetic adsorption to form a carrier assembly. However, because the carrier and base plate are difficult to separate, this invention application is hereby filed. Utility Model Content
[0004] To address the aforementioned problems in the prior art, this invention provides an aluminum alloy magnetic SMT carrier structure that can improve upon these shortcomings.
[0005] This utility model relates to an aluminum alloy magnetic SMT carrier structure, including a thin aluminum alloy carrier and a base plate. The thin carrier is provided with a plurality of first and second hollow holes, and the base plate is provided with a plurality of third hollow holes in a matrix. The bottom surface of the thin carrier is inlaid with sheet metal, and the surface of the base plate is inlaid with a plurality of thin magnets.
[0006] Furthermore, the thin carrier has a left notch on the left side and a right notch on the right side, with the left and right notches positioned asymmetrically.
[0007] Furthermore, the thickness of the thin carrier is 0.06 mm to 0.04 mm, the thickness of the base plate is 1 mm to 2 mm, and the thickness of the magnet is 0.3 mm to 0.7 mm.
[0008] Furthermore, the magnet is fixed with adhesive tape.
[0009] This utility model features an ingenious design and a very simple overall structure. It incorporates a thin-sheet carrier and a base plate, which are fixed together by magnetic attraction. For separation, a left notch is provided on the left side of the thin carrier, and a right notch on the right side; the notches are asymmetrically positioned. This design allows for easy peeling of the carrier and base plate using fingers. Attached Figure Description
