Thinking back to my first day working at an electronics assembly factory, I was hired as a Product Engineer. This role is actually quite similar to that of a Process Engineer, but at that time, Workingbear only had experience in IC packaging or Semiconductor…

The spot market for electronic components is similar to a flea market or second-hand marketplace. The difference is that a flea market mainly sells used items, while the spot market for electronic parts—like MCUs, ICs, MLCCs, capacitors, resistors, indoctors…

在電子產業與科技業，尤其是台灣/中國的電子製造、供應鏈和採購領域，GTK 是一個常見的採購或外包術語的英文縮寫

這篇心得文章來自一位 Podcast 主持人訪談美國當地一間電子代工廠（CM）創辦人的聽後內容整理。他們深入聊

在電子製造業與相關供應鏈管理領域，不管你的工作是工程、採購、PM、還是老闆，多多少少都過「第二供應商（2nd

在電子製造業與相關供應鏈管理領域，「第二供應商（2nd source）」指的是為關鍵零件或材料尋找備用供應來源

“Second-source" qualification usually means that a component has at least two qualified suppliers. The reasons for introducing a second source are straightforward: to deal with material shortages, handle EOL (End of Life) parts, reduce material costs, increase…

As an engineer, Workingbear has to be honest—I really don’t like doing second-source qualification work. It’s time-consuming, stressful, and often thankless. If you do it well, management thinks it’s just part of your job. If it takes too long, they think…
