Problems solved by technology

On the contrary, there will be a pool effect in the central part of the plate. Because the etchant is difficult to be renewed, the etching rate in this area is slower than that of the edge of the plate or the downward side of the plate where the etchant is easy to drain/flow away, and the etching transmission speed is certain. Yes, this will cause the inconsistency between the middle line width and the edge of the product. This phenomenon becomes particularly obvious when making ultra-fi

Example Embodiment

[0020] like figure 2 As shown, a circuit board guide plate includes a flat plate 1, the flat plate 1 is provided with a hollow area 3 for placing products, and the flat plate 1 also includes a fixing device 2 for fixing products.

[0021] The flat plate 1 of the circuit board guide plate can be made of a whole piece of FR-4 (epoxy resin and glass fiber cloth), the thickness of the flat plate 1 is 0.2-2MM, and the shape of the flat plate 1 is "mouth" or square; FR-4 is hollowed out in the middle (ie hollow area 3), and its size can be determined according to the size of the product.

[0022] It is matched with a take-out device for taking out the circuit board from the circuit board guide plate, such as image 3 As shown, including the base 4, the thickness of the base 4 is 5-20MM; the base 4 is provided with a bump 5 for supporting the product, the base 4 and the bump 5 are fixedly connected or integrally formed with each other, and the bump 5 and the The hollow areas 3 of the

Abstract

The invention discloses a circuit board guide board and take-out device and circuit board manufacture method. A circuit board guide board comprises a flat board provided with a hollow area for placing product and a fixing device for fixing product; a circuit board take-out device comprises base provided with a projection for supporting product, base and projection is fixed connected or integrally formed, and projection and hollow area of guide board is corresponding to each other and is of clearance fit. The product is fixed on guide board to enhance the complete evenness and so pool effect will not occur and medicament liquor is quickly cleaned off when product passes the etching line and medicament liquor is sprayed to product surface for reaction, product appearance can keep smoothness and crimpling blocking and resulting waste is prevented during transmitted in the etching line.
