A universal board that can prevent welding penetration

Abstract

The invention discloses a multipurpose plate capable of preventing weld penetration. The multipurpose plate comprises a multipurpose plate body and insertion holes. The insertion holes are arranged in the multipurpose plate body in a matrix manner. The intervals of the horizontal and longitudinal insertion holes are equal. Conductive materials are arranged on the insertion holes. Copper filaments are arranged between the insertion holes and are not in contact with the edges of the insertion holes. According to the invention, during welding of a circuit, according to the circuit design, by connecting the copper filaments with welding feet of electrical appliance components, the circuit can be welded on the multipurpose plate body, and drag welding can be performed on the basis of the copper filaments; there is no need for electric soldering iron to stay on the multipurpose plate body for a long time, so a phenomenon of weld penetration caused by high temperature is avoided; the copper filaments are capable of leading the welding directions of the electric soldering iron, so welding effects are quite attractive and circuit welding can be quite quickly finished; and copper filaments which are not to be welded can be canceled or kept, and requirements on welding levels of a welding worker are not too high, so welding operation is simple.

Description

technical field [0001] The invention belongs to the application field of electronic components and relates to a universal board capable of preventing welding penetration. Background technique [0002] The universal board is a printed circuit board that is covered with pads according to the standard IC spacing, and can be inserted with components and connections according to one's own wishes, commonly known as "hole board". In college students' electronic design competitions, the works usually need to be completed within a few days, so most of them use universal boards. However, the students' welding level is not high, and they cannot correctly grasp the welding speed, welding temperature and straightness of the wiring. Especially when doing soldering with tin connection method, the electric soldering iron needs to melt the solder on the multi-purpose board for a long time to form a circuit. Due to the high temperature of the electric iron, the small copper piece on the uni...

AI Technical Summary

Problems solved by technology

Due to the high temperature of the electric iron, the small copper piece on the universal board was scalded off by the soldering iron head, causing the copper piece to fall off

After the copper sheet falls off, the universal board cannot be stained with solder, and the circuit cannot form a loop, which will cause certain difficulties to the students' circuit welding, and even damage the universal board and cause waste
