Pad-welding structure and debug method applying the same

Abstract

The invention discloses a weld pad structure, and is applicable to a debugging method for a circuit board. The weld pad structure comprises a weld pad body and a blank separation path penetrating the weld pad body, wherein, the blank separation path can separate the weld pad into a first weld pad and a second weld pad; the weld structure further comprises a solder, which covers the blank separation path and the weld pad body selectively; when the solder covers the blank separation path and the weld pad body, the weld pad body can be taken as a path; and when the solder does not cover the blank separation path and the weld pad body, the weld pad body can be taken as an open circuit. A debugging method which applies the weld structure is further disclosed.

Description

technical field [0001] The invention relates to a reworkable welding pad, and in particular to a reworkable welding pad for circuit debugging. Background technique [0002] After the circuit layout and all the processes are completed on the circuit board, in order to avoid problems in the subsequent use of the circuit board, a debugging program is often performed to confirm that all circuit connections and integrated circuits mounted on the circuit board are correct. in normal condition. [0003] Usually, these debugging procedures are carried out in real time after the circuit board layout and process are completed, so the integrated circuits and related circuits required by some debugging procedures will be completed together at the same time as the circuit board is produced, so as to facilitate real-time inspection . In order to avoid the short circuit caused by the direct connection of the line during the debugging test, and to retain the flexibility of rework during t...

Problems solved by technology

Although this method is simple, it needs to consider the cost of purchasing materials, preparing materials, and packaging of zero-ohm resistors.
