Mr. Aki! My brain is getting overheated!

Okay, we shall stop here. The next process after annealing is winding process.

In winding process, the prescribed wire length shall be wound on the spool like in Fig.1. Generally, winding length per spool is ranging from 100m〜10,000m but subjected to customer’s requirement. Winding may sound simple but Au bonding wire can be broken with so small as a few grams of load. However, pulling load is essential to wind the wire properly. Otherwise, it may be loosened and entangled during the transportation. Once it happens, the wire can not be used at our customers. You know, the winding is absolutely delicate process.

Oh ! Really. Please share with me more interesting topics next time. Thank you, Mr. Aki!, Dr. Yama!
