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 short circuit caused by carbon oil leakage. The circuit board comprises adjacent bonding pads pre-printed with carbon oil, and the circuit board printing method for preventing short circuit caused by carbon oil leakage comprises the following steps: arranging a solder bridge: arranging an isolation bridge for isolating the carbon oil between the adjacent bonding pads pre-printed with the carbon oil, wherein the isolation bridge prevents short circuit caused by carbon oil seepage after the bonding pad is printed with the carbon oil; baking the circuit board: baking the circuit board after the circuit board pattern is manufactured; and printing carbon oil: printing the carbon oil on the bonding pad, needing to be printed with the carbon oil, of the circuit board. According to the circuit board printed by the circuit board printing method for preventing the short circuit caused by the carbon oil leakage, the conductive short circuit of the circuit board caused by the carbon oil leakage in the use process is avoided.
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.
