Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board carriers, specifically to an SMT carrier assembly. 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 utility model provides an SMT carrier assembly that can improve upon the above deficiencies.
[0005] This utility model relates to an SMT carrier assembly, including a thin aluminum alloy carrier, a base plate, and a skid. The thin carrier has multiple first and second perforations, and the base plate has multiple third perforations arranged in a matrix. A sheet metal is embedded in the bottom surface of the thin carrier, and multiple thin magnets are embedded in the surface of the base plate. The thin carrier has a left notch on the left side and a right notch on the right side. A groove is provided at the position of the right notch on the base plate. The skid is detachably disposed in the groove.
[0006] Nearly half of the pry bar is T-shaped and includes a handle and a triangular prism, the thickness of which is less than the depth of the groove surface.
[0007] Furthermore, the end face of the triangular prism is an obtuse isosceles triangle.
[0008] 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.
[0009] Furthermore, the magnet is fixed with adhesive tape.
[0010] This utility model has a clever design and a very simple overall structure. It features a thin carrier and a base plate, which are fixed together by a thin magnetic adsorption mechanism. The thin carrier has a left notch on the left side and a right notch on the right side. A groove is provided on the base plate at the position opposite to the right notch, and the pry bar is placed in the groove. Attached Figure Description

[0014] Illustration: 1 Thin sheet carrier, 10 Sheet iron, 2 Base plate, 21 Thin magnet, 3 Right side notch, 31 Left side notch, 4 First hollow hole, 5 Second hollow hole, 6 Third hollow hole, 7 Slide, 8 Handle, 9 Triangular prism. Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0016] like Figure 1-3 As shown, this utility model relates to an SMT carrier assembly, including a thin aluminum alloy carrier 1 and a base plate 2. The thin carrier is provided with a plurality of first hollow holes 4 and second hollow holes 5. The base plate is provided with a plurality of third hollow holes 6 in a matrix. The bottom surface of the thin carrier is inlaid with sheet metal 10. The surface of the base plate is inlaid with a plurality of thin magnets 21. The left side of the thin carrier is provided with a left notch 31 and the right side is provided with a right notch 3. The right notch is located at a position opposite to the base plate and a groove 7 is provided. The pry bar is detachably disposed in the groove.
[0017] Furthermore, the pry bar is T-shaped and includes a handle 8 and a triangular piece 7, the thickness of which is less than the depth of the groove surface.
[0018] Furthermore, the end faces of the triangular prism are obtuse-angled isosceles triangles. A cleverly designed pry bar is used to separate the thin carrier and the base plate; its operation is ingenious and simple.
[0019] 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.
[0020] Furthermore, the magnet is fixed by adhesive tape, and a corresponding shallow groove is set on the surface of the base plate. The tape is placed in the shallow groove, and the base plate can be separated by the left and right notches during separation.
[0021] This solution utilizes a skid design to achieve rapid separation of the thin carrier and the base plate, improving maintenance and replacement efficiency. The magnet is secured with adhesive tape, and shallow grooves are created on the base plate surface to accommodate the tape. During separation, the base plate can be detached via left and right notches. This design simplifies magnet replacement and maintenance.
