Abstract
The invention relates to the technical field of PCB manufacturing, and provides a resin plug hole process. The process comprises the following steps: placing steel bars, at least two steel bars whichare parallel to each other are placed on the surface of a machine table at intervals; placing air guide cushion plates, the air guide cushion plates with air guide holes are placed on the steel bars,a channel communicated with the outside air is formed by the machine table surface, air guide cushion plates, and steel bars, and the air guide holes are communicated with the channel; placing circuitboards, the circuit boards with holes to be plugged are arranged on the air guide cushion plates; placing an aluminum sheet, the aluminum sheet with windows is placed on the circuit boards; scrapingresin, the windows are opposite to the hole to be plugged, the holes to be plugged are opposite to the air guide holes, the resin covering the aluminum sheet is scraped to the windows through a scraper, and the resin is plugged into the holes to be plugged through the windows. According to the resin plug hole process, the air guide property of the air guide cushion plates is improved, so that thequality of the resin plug hole is improved.
Description
technical field [0001] The invention belongs to the technical field of circuit board manufacturing technology, in particular to a technology for plugging holes with resin. Background technique [0002] The process of resin plugging holes is to reduce the design size of PCB and improve the wiring capability of PCB. The process of resin plugging includes drilling, electroplating, baking, and grinding. The specific process is to drill holes on the PCB and then plate the holes, then fill the holes with resin and bake, then grind the resin and smooth it , Finally, a layer of copper is plated on the resin, the effect is that the hole can be conducted, and the surface is flat, and normal wiring can be performed. In the production process, it is necessary to focus on controlling and paying attention to the fullness of the hole to be plugged and the air bubbles in the hole. If the resin plug hole is not plugged well or the hole to be plugged is not full, the copper plating on the ho...
