Description
Technical Field
The invention relates to the technical field of machinery, in particular to an accelerometer binding post fixing device.
Background
The quartz flexible accelerometer is provided with 5 wiring columns in total, the surfaces of the wiring columns are plated with gold, one end of each wiring column is arranged in the watch core and is bonded with the pendulous reed through a gold wire, and the other end of each wiring column is arranged outside the watch core and is connected with the integrated circuit through an enameled wire. The principle of gold wire bonding is that firstly, a gold wire is melted to form a gold wire ball, and then a chopper drives the gold wire ball to bond the gold wire to the end face of the binding post by applying certain pressure, ultrasonic energy and thermal friction. Under an ideal state, the surface of the binding post is flat, the quality of the coating is good, the stripping and falling phenomena are avoided, and the gold wire is firmly bonded on the end face of the binding post. In practice, the terminal is extremely fine, the processing technology is required to be high in precision, the end face is observed to be in a vortex shape under a microscope, and the contact area of a solder ball is small when a gold wire is welded. The binding post is made of kovar alloy, the surface gold plating is solution gold plating, various ions in the solution are easily adsorbed on the binding post, so that the gold plating layer has more impurities, and the situation that a gold ball cannot be transferred to the end face of the binding post can occur during bonding.
At present, in order to prevent the phenomenon that gold wire bonding is unsuccessful, the weldability of the binding post is tested in small batches, in the welding process, the chopper vibrates continuously, if the fixing clamp is not tightly matched with the binding post, the binding post vibrates along with the chopper, energy cannot be transmitted to the gold wire ball through the chopper, and welding cannot be finished. Therefore, increasing the degree of fixing firmness of the terminal can increase the success rate of welding. Because the gold wire ball bonding is also the process of forming a molten alloy layer on the end face of the gold wire ball and the end face of the binding post, the temperature of the workpiece is increased in practice, and the welding success rate is improved. Original terminal fixed frock is the round hole, if the terminal cooperation is too tight, it is comparatively difficult subsequently to take out the terminal, if the cooperation is not tight, can't accomplish the welding to do not have heating temperature regulating device, original terminal mounting fixture verifies that the yield is on the low side, consequently, need a novel messenger's tolerance in-range terminal homoenergetic that takes the heating closely cooperate, and the terminal is got and put easily, does not harm the terminal mounting fixture of surperficial gold-plated layer.
