Embodiment Construction

[0015] The present invention is mainly used in the manual cutting process of PCB boards, and provides a circuit board cutting process. The specific steps are as follows:

[0016] Step 1. The operator must wear the electrostatic ring to work, and ensure that the electrostatic ring and the electrostatic line are connected reliably. The foot cutting station is equipped with a foot cutting cover, and then take out the furnace carrier carrying the product from the assembly line at the connection section behind the tin furnace;

[0017] Step 2. Take out the product from the furnace carrier, and confirm whether the temperature of the front and back of the PCB board is too high;

[0018] Step 3. Put the furnace-passed carrier on the belt of the recovery line, and flow to the first station of the plug-in;

[0019] Step 4. Confirm the part feet on the tin surface of the product to ensure that the parts feet are within the range of 0.8~2.0mm. The parts feet exceeding 2.5mm need to be cut...

Abstract

The invention provides a circuit board pin-shearing process used for a manual pin-shearing process of a PCB. The beneficial effects of the process are that redundant pins of multiple components are sheared by employing the pin-shearing process to achieve the length required by a fabrication process, the production process is accelerated, the labor intensity is reduced, the production efficiency isimproved, the process is strictly required, the product quality is improved, the quality of the pin-shearing operation is guaranteed, the damage to the components during pin shearing is avoided, human accidents and strains are eliminated, and soldering spots with pin shearing avoid the soldering crack or scratch of copper foils.

Description

technical field [0001] The invention relates to the electronics industry, in particular to a circuit board element cutting process. Background technique [0002] The electronics industry has always been a technology-intensive and labor-intensive industry. Through-hole mounting technology is the foundation of the electronics industry, and manual foot cutting technology has always been the foundation of China's electronics industry. From the perspective of the technological development trend of electronic components in the world, generally speaking, chip has become one of the important symbols to measure the development level of electronic component technology. Among them, chip inductors, chip resistors, and chip inductors are three passive Components account for about 85%-90% of the total output of components. Electronic components are also rapidly developing toward miniaturization while being chipped. With the acceleration of the miniaturization process of electronic equip...
