The invention provides an actual brushing force capable of detecting a brush to ensure that the solder ball of the electronic component performs the brushing operation under an appropriate brushing force, and effectively reduces the damage rate of the electronic component, thereby improving the detection quality and the cost saving brushing force. Detection device.

Nowadays, the electronic components with tin balls are becoming more and more precise and lightweight. The ball-making process of electronic components is to implant a plurality of array-arranged solder balls (also called solder balls) on the substrate by a ball-planting machine, and then the re-welding machine will Each solder ball is soldered to the substrate to complete the ball-planting operation. Since the reflowing operation is liable to be poorly placed due to temperature, impurities or solder balls, some of the solder balls cannot be soldered to the substrate. Therefore, the manufacturer ensures the electronic components. Quality, that is, the solder ball inspection operation with the brush detection device to detect the solder ball's fixedness, and eliminate the defective product; please refer to Figure 1, which is the Taiwan invention No. 90103773 "ball grid array package unit" The solder ball inspection method is provided with a feeder 11 for carrying the electronic component 12 of the solder ball 121, and a driving source is provided above the traveling path of the feeder 11. The rotating brush 13 is used to check whether the solder ball is soldered. When performing the inspection operation, the feeder 11 carries the electronic component 12 through the brush 13, and the brush 13 scans the solder ball on the electronic component 12. 121, if the solder ball 121 has a lower bonding strength With the brushing force of 13, the brush 13 is brushed off, and the defective solder ball 121 is eliminated. If the soldering strength of the solder ball 121 is higher than the brushing force of the brush 13, the brush 13 will pass smoothly. The solder ball 121 of the good product achieves the purpose of inspecting the solder ball; however, when the brush 13 scans the solder ball 121 on the electronic component 12, the brush ball 121 is generated, because the solder ball 121 on the electronic component 12 is equivalent. Tiny, different sizes of solder balls 121 also bear different brushing power. If the brushing force of the brush 13 is too large, although the solder ball 121 of the defective product can be removed, the solder ball 121 of the good product is also damaged. If the force is too small, the solder ball 121 of the defective product cannot be removed, thereby affecting the quality of the solder ball inspection. Therefore, when performing the solder ball inspection operation, the brushing force of the brush 13 must be accurately set to ensure the inspection quality, but this inspection is performed. The device is not designed to detect the actual brushing force of the brush 13, so that it is impossible to know whether the brushing force of the brush 13 is suitable for brushing the type. The solder ball 121 of the type is such that the quality of the inspection cannot be ensured and the solder ball is prevented from being damaged, which needs to be improved.
