It is necessary to consider whether the copper will be exposed when the gong groove is shaped, and move the drilled half-hole into the unit. <br>he right hole is drilled first, and then the board is turned over (or mirrored) and the left hole is drilled to reduce the pulling of the copper of the inner hole of the half hole by the drill, resulting in the lack of copper of the hole. <br>The size of the drill nozzle for drilling the half hole depends on the spacing of the contour lines. <br>Draw the solder mask film, use the gong space as a stop point and open the window to increase 4mil treatment. <br>The Designer&#039;s Suggestion When Designing The Circuit <br>Change the distance from the edge line to the hole center. The general design is to place the hole center on the edge line and move the control center down. For example, the diameter of the hole is 1.4mm, the distance between the two holes is 2.54mm, and the board edge The distance between the line is 0.33mm from the center of the through hole, and the thickness of the plate is 0.6mm. The angle between the tangent to the cut point of the wall and the track of the milling cutter was 90 degrees before, but this time it is about 60 degrees. Because the board edge line is at a certain distance from the center of the through hole, the cutting angle of the milling cutter is changed, and the board thickness is extremely small, so the copper in the hole is not easily pulled out. The simultaneous improvement of small batch pcb design and production can greatly improve the production yield of PCB half-hole boards. <br> <br>As a pcb board maker, we will do our best to meet all the needs of customers. <br>#half#hole#pcb <br>[a]https%3A%2F%2Fwww.hhcircuits.com%2Fhalf-hole-through-hole-pcb[/a]
