Ten Points to Note on B Imposition
Zhongtian Yuan Circuit Board Co., Ltd. is a high-tech enterprise in Zhengzhou specializing in the R&D, production and processing of B circuit boards, multi-layer printed boards, and aluminum substrates.
. The outer frame (clamping edge) of panel B should adopt a closed-loop design to ensure that panel B will not deform after being fixed on the fixture
. The width of panel B (line) or 3 (line) If automatic dispensing is required, the width and length of the B panel
The shape of the B panel should be as close to a square as possible. It is recommended to use, Between
, when setting the reference positioning point, usually leave a larger non-solder mask area around the positioning point
, between the outer frame of the panel and the internal small board, and between small boards There should be no large components or protruding components near the connection points, and there should be a space larger than . Make four positioning holes. The hole diameter and strength of the holes should be moderate to ensure that they will not break during the loading and unloading process. The hole diameter and position accuracy should be high. The hole walls should be smooth and without burrs
. Each small plate in the B puzzle should be at least There must be three positioning holes with a diameter of 3. No wiring or patching is allowed in the edge positioning holes
. It is used for the whole board positioning of B and the reference symbols for the positioning of fine-pitch devices. In principle, the spacing is less than. The positioning reference symbols for imposition of B sub-boards should be set at their diagonal positions and should be used in pairs and arranged at the diagonal corners of the positioning elements
. Large components should have positioning posts or holes. Key points Such as/interface, microphone, battery interface, micro switch, headphone interface, motor, etc.
