Description

Technical Field

[0001] The present invention relates to the technical field of printed circuit boards, and in particular to a PCS printing preparation device and method. Background Art

[0002] At present, SIP (System In Package) products are generally produced by SMT2 (Surface Mount Technology). In the production process, most of them adopt PCS (PCB single board) panelization process, which is produced by PCS printer equipped with vacuum printing base and carrier for placing SIP. The vacuum printing base has a boss structure, and the boss passes through the carrier to lift up a single SIP product. After the SIP product is lifted up, it contacts with the steel mesh to complete printing. There is a large gap between the bosses. When the steel mesh is printed, the scraper passes through the boss gap area. Due to the printing pressure of the scraper, the steel mesh will be deformed and stretched downward, resulting in a slight displacement. After the scraper scrapes through the printing area, a blurred print is obtained. Therefore, the current printing method cannot meet the demand for high-precision prints. Summary of the invention

[0003] In view of the above problems, an object of the present invention is to provide a PCS printing preparation device and method to solve the problem that the existing PCS preparation equipment cannot meet the demand for high-precision printed products.

[0004] The present invention provides a PCS printing preparation device, which prepares a PCB by scraping a scraper across a printing area, comprising: a carrier plate for placing a SIP, a vacuum printing base, the carrier plate is provided with product profiling grooves evenly and at intervals, the vacuum printing base is provided with bosses evenly and at intervals, the product profiling groove is used to place the SIP and is adapted to the boss, the boss is used to eject the SIP placed in the product profiling groove, wherein:

[0005] Avoidance grooves are arranged between adjacent product-profiling grooves, and support bars are arranged between adjacent bosses;

[0006] The avoidance groove provides an avoidance space for the support bar and is adapted to the support bar, and the support bar is used to provide support for the scraper to move between adjacent bosses.

[0007] Preferably, the carrier includes a main body and a frame arranged around the main body, wherein:

[0008] The product-profiling grooves and the avoidance grooves are respectively evenly and spaced apart from each other on the main body.

[0009] Preferably, the support bar comprises an extension portion and a support body; wherein,

[0010] The extension parts are respectively arranged on both sides of each boss, and adjacent bosses are connected via the extension parts and the support body arranged between the two extension parts.

[0011] Preferably, the shape of the portion where the extension portion is connected to the support body matches the shape of the support body.

[0012] Preferably, the boss, the extension portion and the support body are an integrally formed structure, or the boss, the extension portion and the support body are separate structures.

[0013] Preferably, adjacent product-profiling grooves are connected through the avoidance groove. Preferably, the support strip comprises extensions respectively arranged on both sides of each boss, and the extensions of adjacent bosses are arranged discontinuously.

[0014] Preferably, the boss and the extension portion are an integrally formed structure, or the boss and the extension portion are separate structures.
