摘要

本研究以導入覆晶載板新超微小鑽徑機械鑽孔製程為主要目的，因機械鑽孔製程一直以來是覆晶載板工作站的瓶頸製程，為了提升產能且在整個機械鑽孔過程中能達到品質要求，藉由量產環境下進行鑽孔實驗以及運用小量試產的結果作驗證。

為了找出機械鑽孔製程所延伸的孔壁粗糙度及孔位精度問題，先經由實際機械鑽孔生產程序觀察對加工過程中影響品質特性的重要關鍵因子，本實驗以主軸轉速、進刀速、退刀速、鑽針、鋁蓋板為重點參數設計。尋求一組新超微小鑽徑機械鑽孔製程參數設定值符合量產上需求。運用JMP統計軟體得到一組參數值設定為主軸轉速200krpm、進刀速46mm/sec、退刀速400mm/sec、鋁蓋板LE450、鑽針K牌。

本實驗結果顯示使用參數值在小量試產得到孔壁粗糙度及孔位精度CPK符合機械鑽孔製程量產環境需求，且機械鑽孔製程單機產能由每月0.085KK提升至每月0.122KK機械鑽孔機台需求量明顯減少的成效。

The purpose of the study is to introduce a machine micro-drilling process into flip-chips to increase the capability for machine micro-drilling process has constantly been a bottleneck process in the flip-chip workstations. For the purpose of enhancing capability and achieving the quality requirements in the machine micro-drilling process, a design of experiment was conducted in the environment of mass production to gain the results of the best performance, which were later verified by small-scale production.

In order to detect the problems of roughness and accuracy caused by machine micro-drilling process, the key factors which affect the product quality were first discovered by observing the producing procedures. Afterwards, five factors were determined in the design—spindle speed, infeed rate, retract rate, the brand of drill bit, and entry board. With the use of JMP statistics software, an appropriate set of parameters which meet the requirements of mass production was obtained—200 krpm for spindle speed, 46 mm/sec for infeed rate, 400 mm/sec for retract rate, LE450 for entry board, Brand K for drill bit.

In addition, the application of the set of the parameters on the small-scale production resulted in that the requirements of mass production in machine micro-drilling process were met in terms of roughness and accuracy. Meanwhile, the capability of a single micro-drilling machine was enhanced from 0.085KK per month to 0.122KK per month, which significantly reduces the demand of the machines.
