Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0019] Such as figure 1 Shown, the present invention provides a kind of circuit board printing method that prevents carbon oil seepage short circuit, described circuit board includes the adjacent welding pad of pre-printed carbon oil, prevents the circuit board printing method of carbon oil oil seepage short circuit comprising Follow the steps below:

[0020] Step 100: setting up an isolation bridge, that is, an isolation bridge for isolating carbon oil is provided between adjacent pads of pre-printed carbon oil, and the isolation bridge prevents the pads from printing carbon oil and exuding carbon oil to conduct electricity. During the use of the circuit board, carbon oil will usually seep out of the pads printed with carbon oil, and the seepage of carbon oil will usually lead to a conductive short circuit between adjacent pads.

Abstract

The invention relates to a circuit board printing method for preventing carbon oil leakage short circuit. The circuit board comprises adjacent soldering-pans pre-printed with carbon oil. The circuit board printing method for preventing the carbon oil leakage short circuit comprises the following steps of: arranging solder bridges: arranging isolation bridges for isolating the carbon oil between the adjacent soldering-pans pre-printed with the carbon oil, wherein the isolation bridges prevent the soldering-pans printed with the carbon oil from leaking the carbon oil and generating short circuit; baking the circuit board: after making a circuit board pattern, baking the circuit board; and printing the carbon oil: printing the carbon oil on the soldering-pans of the circuit board required to be printed with the carbon oil. The circuit board printed by the circuit board printing method for preventing the carbon oil leakage short circuit cannot generate conducting short circuit due to carbon oil leakage in the using process.

Description

technical field [0001] The invention relates to a circuit board printing method and a circuit board for preventing carbon oil leakage and short circuit, in particular to a circuit board printing method and circuit board with adjacent pads for preventing carbon oil leakage and short circuit. Background technique [0002] With the development of circuit board technology, carbon oil circuit boards came into being. Carbon oil circuit board is to print carbon oil on some solder joints or pads of the circuit board. Printing carbon oil on the circuit board can make the printed carbon oil part conductive, and also has the effect of wear resistance and corrosion resistance. . Since carbon oil conducts electricity, when the circuit board parts that need to be printed with carbon oil are adjacent and the distance is relatively close, it is easy to generate a conductive short circuit due to oil leakage of carbon oil during the production process.
