| titleOfInvention | Printed circuit board pad for radio frequency calibration |
| abstract | The utility model discloses a printed circuit board pad for radio frequency calibration, including printed circuit board, reverse side pad, positive pad and protection casing, reverse side pad sets up at the lower extreme of setting at printed circuit board for connect electron device or be used for the circuit of radio frequency calibration. The utility model discloses a printed circuit board pad for radio frequency calibration, at first, can protect reverse pad, welder can not touch reverse pad during welding, the condition that reverse pad is heated the high temperature and drops is avoided appearing, secondly, can make the even junction that falls to reverse pad and welding device of soldering tin liquid, the solder joint of formation is more even, stability is relatively good, the condition that the soldering tin liquid splashes other positions of circuit board can not appear plump, and finally, people's hand can be scalded to high temperature when can avoiding welding, and can live the pin parcel of reserving, the pin of avoiding reserving harms people's hand, bring better use prospect. |
