Abstract

The invention discloses a manufacturing method of a medical instrument detection plate. The manufacturing method comprises the following steps: (1) performing cutting; (2) carrying out inner-layer patterning, inner-layer etching and internal inspection; (3) pressing a multilayer substrate into a whole board, drilling after pressing, and then carrying out copper deposition or board electrification;(4) etching a circuit pattern (1) , etching (1), wherein the interval between the bonding pads is etched, and the interval between the bonding pads is a solder mask area between the adjacent bondingpads; (5) performing resin hole plugging, wherein the resin hole plugging sequentially comprises the following steps of aluminum sheet hole plugging, pre-baking, resin silk-screen printing, board copying and resin grinding; (6) etching the circuit pattern (2); and (3) etching; (7) carrying out AOI (2) solder mask, character and surface treatment; and (8) forming, testing, FQC and packaging. According to the invention, the resin ink is silk-screened at the bonding pad interval between the adjacent bonding pads, so that the solder mask layer in the solder mask area can be prevented from fallingoff, and the product reliability is improved.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a manufacturing method of a medical instrument detection board.
