Description

Technical Field

[0001] The utility model relates to the technical field of circuit board cleaning, in particular to an endoscopic cleaning machine for circuit boards. Background Art

[0002] With the continuous development of electronic technology, multi-layer printed circuits are rapidly developing towards high density, high precision, and high-layer digitalization. Circuit boards are divided into three major categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards. Multi-layer boards refer to printed boards with more than three layers of conductive graphic layers and insulating materials in between, and the conductive graphics in between are interconnected as required. The production method of multi-layer boards is generally to make the inner layer graphics first, and then use the printing and etching method to make a single-sided or double-sided substrate, and put it into the specified interlayer, and then heat, pressurize and bond it. It has high assembly density, small size, and light weight. Due to the high assembly density, the connection between the components is reduced, thus improving reliability;

[0003] After searching, the authorization announcement number in the prior art is: CN208810721 U, which discloses an energy-saving cleaning machine for circuit boards, including a shell, an ultrasonic generator is fixedly connected to the central axis of the bottom of the inner cavity of the shell, ultrasonic transducers are fixedly connected to both sides of the ultrasonic generator, the top of the ultrasonic transducer is fixedly connected to the shell, and the top of the shell is movably connected to a top plate. The utility model solves the problem of low cleaning efficiency caused by the circuit boards fitting each other when the existing energy-saving cleaning machine for circuit boards cleans multiple circuit boards at one time through the coordinated use of a locking block, a first clamping block, a second clamping block, a first spring, a clamping block, a movable rod, a clamping slot, a connecting plate, a connecting rod, a second spring, a fixed rod and a movable slot. The energy-saving cleaning machine for circuit boards has the advantage of high cleaning efficiency, and the circuit boards can be fixed individually when cleaning, thereby improving the practicality of the energy-saving cleaning machine for circuit boards, and is worthy of promotion.

[0004] The above patent still has some problems when in use.

The circuit board needs to be taken out to observe whether the circuit board is cleaned. Therefore, we need to propose a circuit board endoscopic cleaning machine. Utility Model Content
