Title:
METHOD FOR ACQUIRING PATTERN PLATING PARAMETER
Document Type and Number:
WIPO Patent Application WO/2017/167253
Kind Code:
A1
Abstract:
Disclosed is a method for acquiring a pattern plating parameter, comprising the following steps: acquiring the plating area of an SS surface, the plating area of a CS surface, the current setting density of the SS surface and the current setting density of the CS surface; calculating, according to the plating area of the SS surface, the plating area of the CS surface, the current setting density of the SS surface and the current setting density of the CS surface, the actual current density of the SS surface and/or the actual current density of the CS surface according to a first internal algorithm; and substituting the actual current density of the SS surface and/or the actual current density of the CS surface and a plating time of a metal to be plated into a Faraday formula H = κ·D·η·t to obtain a plating thickness H of the metal plated on the SS surface and/or the CS surface of a circuit board. According to the method for acquiring a pattern plating parameter, the actual plating thickness of a welding surface and that of an insert surface can be obtained before a circuit board is plated, and a current density parameter can also be obtained through backstepping according to the plating area and the plating layer thickness of the welding surface and those of the insert surface, so that the setting accuracy of a production parameter of the circuit board is relatively high.
