Problems solved by technology

However, during the processing of this type of PCB board, it is often caused by problems such as electroplating swings during the electroplating process or in the process of picking and placing the board, which can easily cause the connecting ribs to be broken and the board to be scrapped, which increases production costs and greatly reduces production efficiency. Production has caused great trouble

Abstract

The invention provides a PCB (Printed circuit board) breakage prevention milling and plating slot and an application method of the PCB (Printed circuit board) breakage prevention milling and plating slot. The PCB (Printed circuit board) breakage prevention milling and plating slot comprises a slot body. The slot body comprises unit slots (1), a slot bottom and a slot wall surrounding the slot bottom. The slot wall comprises a first slot wall (21) and a second slot wall (2). At least two stress unloading slots (3) are arranged between the first slot wall and the second slot wall. Slot holes (4) are arranged between the unit slots and the second slot wall. The stress unloading slots are correspondingly arranged at one side of the slot holes. According to the slot and the method, when electroplating rock is generated and when the board is fetched and placed, connection ribs are avoided from being scraped due to breakage, the breakage results from centralized stress on the connection ribs. The production cost is effectively reduced. The production efficiency is improved.

Description

technical field [0001] The invention relates to a PCB board manufacturing process, in particular to a milling and plating groove for a PCB anti-breakage board and an application method thereof. Background technique [0002] Printed circuit boards, also known as printed circuit boards, printed circuit boards, often use the English abbreviation PCB (Printed circuit board), with insulating boards as the base material, cut to a certain size, with at least one conductive pattern attached to it, and holes (such as component holes, fastening holes, metallized holes, etc.), used to replace the chassis of electronic components installed in the past, and to realize the interconnection between electronic components. In contemporary times, circuit panels only exist as effective experimental tools, and printed circuit boards have become an important part of the electronics industry. [0003] The traditional printed circuit board (PCB) production adopts the jigsaw design. Multiple PCB de...
