Printed circuit board production and manufacturing process

Abstract

The invention provides a printed circuit board production and manufacturing process. The printed circuit board production and manufacturing process is completed through cooperation of a drying frame,a positioning unit, a driving unit, two side face drying units, a connecting plate, a pushing air cylinder and an inserting type drying unit. According to the printed circuit board production and manufacturing process, the problems that in the mode of fixing four corners through screws, the time for a single circuit board is long, assembly line production is not suitable, the screw fixing mode maydamage the surface of the circuit board, the position of the circuit board is always unchanged in the drying process, and most of hot air blows from the periphery to the middle, uneven heating of thesingle circuit board, different heating degrees of circuit boards at different positions and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of printed circuit board production and manufacturing, in particular to a printed circuit board production and manufacturing process. Background technique [0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. The main advantage of using circuit boards is that they greatly reduce wiring and assembly errors, and improve automation and productivity. Printed circuit boards usually refer to The bare board is a circuit board without components. In the production process of the circuit board, it needs to be baked, and the organic solvent in the liquid ink is evaporated to solidify by using high-temperature hot air circulation. The traditional drying method Usually, the circuit board is placed on a baking rack for drying. However, during hot air drying, since the circuit board is light in weight, it cannot support the weight by itsel...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a printed circuit board manufacturing process, which can solve the problem of fixing the four corners with screws, which takes a long time for a single circuit board, is not suitable for assembly line production, and the way of screw fixing may damage the circuit board The surface, and the position of the circuit board during drying is always the same, and the direction of the hot air is mostly blown from the surrounding to the middle, resulting in uneven heating of a single circuit board and different heating degrees of circuit boards in different positions.
