Problems solved by technology

The above-mentioned small copper block fixing method has the following disadvantages: the metal copper block is easily separated from the tape and lost due to the impact of roller transmission, liquid impact, water washing pressure, and wind blowing pressure; the glue on the exposed high-temperature tape will stick when browning. On the roller, it brings hidden dangers to the production of other production boards; this method cannot be reused, the labor input is large, and the production efficiency is low

Embodiment Construction

[0012] refer to figure 1 , a circuit board processing jig for browning copper blocks according to the present invention includes a supporting plate 1, and a plurality of accommodating cavities 2 for accommodating copper blocks are separated on the supporting plate 1, and the size of the accommodating cavities 2 can be determined according to the actual situation. The size of the browned copper block is designed in different specifications to meet the browning requirements of copper blocks of different sizes. The bottom of the accommodation chamber 2 is respectively provided with a plurality of through holes 3. Preferably, the through hole at the center of the bottom of the accommodation chamber 2 Hole 3 is a strip hole, and the through holes 3 at the four corners are round holes. The through hole 3 at the bottom is to facilitate the exchange and outflow of browning liquid, improve the quality of browning and avoid affecting the operation of subsequent processes. The center of t...

Abstract

The invention discloses a circuit board processing tool for copper block brown oxidation. The circuit board processing tool comprises a support plate, a plurality of accommodating cavities used for accommodating copper blocks are arranged on the support plate at an interval, bottom parts of the accommodating cavities are respectively provided with a plurality of via holes, and side walls of the accommodating cavities are provided with grooves. In the circuit board processing tool for copper block brown oxidation, the accommodating cavities of different specifications can be designed based on sizes of the copper blocks to be brown oxidized, requirements for brown oxidation of the copper blocks of different sizes can therefore be met, a horizontal brown oxidation line can be crossed via a normal PCB board brown oxidation mode, brown oxidation of other PCB boards cannot be affected, the circuit board processing tool is simple in structure and low in cost, the circuit board processing tool can be reused for many times, and the circuit board processing tool is convenient to operate and good in wearing property.

Description

technical field [0001] The invention relates to a jig used in the production process of PCB boards, in particular to a jig for processing circuit boards of browned copper blocks. Background technique [0002] At present, embedding metal copper blocks with good thermal conductivity in the PCB is a heat dissipation method to improve heat dissipation performance. Before the buried copper block PCB board is pressed, the embedded metal copper block needs to be browned to clean and roughen the surface of the copper block and improve the bonding force between the metal copper block and the resin. At present, most of the browning production lines in PCB factories are designed with horizontal roller transmission, and the minimum processing size is 200mm×200mm. For copper blocks whose size exceeds the capacity of the browning production line equipment, if the browning is carried out directly, it is very easy to jam the wire and drop the cylinder. Even browning failed. The current co...
