Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board baking technology, specifically a baking device for circuit board processing. Background Technology
[0002] Circuit boards may absorb moisture from the air during storage or transportation. If soldering is performed directly, the high temperature will cause the moisture to evaporate, resulting in defects such as bubbles, poor soldering, or delamination at the solder joints.
[0003] Chinese patent disclosure (CN220304171U) discloses a baking device for circuit board processing. The device includes a housing, with a motor fixedly connected to the bottom left side of the housing. The output end of the motor passes through the housing and is fixedly connected to a first rotating rod. A first pulley is fixedly connected to the bottom of the first rotating rod. A second rotating rod is rotatably connected to the bottom right side of the inner side of the housing. A second pulley is fixedly connected to the bottom of the second rotating rod. Support rods are fixedly connected at equal intervals to the first and second rotating rods. A U-shaped frame is fixedly connected to the other end of each support rod. In this invention, the circuit board is placed between two clamping plates and fixed by spring force. Starting the motor, in conjunction with the first rotating rod, first pulley, belt, second pulley, and second rotating rod, drives the circuit board to rotate. A fan and heating plate are activated to bake the circuit board, eliminating the need for manual flipping.
[0004] However, the device still has the following drawbacks: when in use, the heating rod and fan are activated to bake the circuit boards, but the temperature of the bottom circuit boards is different from that of the top circuit boards, resulting in different baking effects for the top and bottom circuit boards. Therefore, we propose a baking device for circuit board processing to solve this problem. Utility Model Content
