Method for producing circuit board thin plates

The invention discloses a method for producing circuit board thin plates. The technical scheme is characterized in that the method comprises the following steps that: conducting plating though holes; conducting outer layer circuit pattern transfer; conducting graph electric plating and etching; penetrating a string through locating holes of the circuit board thin plates, utilizing string beads to separate the circuit board thin plates, and plating the circuit board thin plates though the holes, after plating the circuit board thin plates through the holes, washing liquid medicine on the surfaces of the circuit board thin plates away by horizontally drawing the circuit board thin plates through a thick plate; conducting electric test; conducting routing; utilizing a plastic package tray to package a finished-product unit plate subjected to routing. From the procedure of layer circuit pattern transferring to the procedure of routing, the circuit board thin plates are compressed through pressing grooves by the adoption of a pig cage frame device to be transferred between the procedures. The method for producing the circuit board thin plate solves the problems that the circuit board thin plates are prone to plate adhesion, plate curving, plate clamping and plate fracture due to the fact that the circuit board thin plates are small in size.
