Experience

• Manager, NPI for MEMS BU Carsem Sdn. Bhd. · Full-time Mar 2015 – Present 11 yrs 3 mos Ipoh, Perak, Malaysia MEMS NPI Design Engineer & Manager
  As an NPI Design Engineer and Section Manager specializing in Micro-Electro-Mechanical Systems (MEMS), I operate at the elite intersection of advanced micro-electronics layout architectures and large-scale industrialization. My career is defined by taking highly complex, next-generation MEMS concepts through the rigorous New Product Introduction (NPI) pipeline and successfully qualifying them for flawless, zero-defect high-volume manufacturing (HVM). I don't just create layouts that look perfect on screen; I design for scalability, long-term reliability, and customer-accepted yield parameters. Managing a dedicated engineering section has given me deep cross-functional command over the entire product lifecycle—from initial structural configuration and mask layout optimization to defining strict qualification protocols that eliminate processing leakage and design-induced manufacturing failures before they hit the assembly floor
• Sr. Process Engineer (Mold) Carsem Sdn. Bhd. · Full-time Mar 2015 – Mar 2018 3 yrs Ipoh, Perak, Malaysia Sr. Mold Process Engineer
  As a Senior Process Engineer specializing in advanced semiconductor encapsulation and molding, my expertise lies at the critical forefront of manufacturing execution, product yield optimization, and continuous process improvement. Rather than just drafting lines, my career has been dedicated to ensuring that physical products meet exact, high-performance output criteria and strict customer-accepted quality yields. I understand exactly how physical variables—such as mold temperatures, transfer pressures, clamp forces, and compound flow behaviors—directly dictate the success or failure of a semiconductor package. On Cad Crowd, I serve as a highly specialized technical consultant and validator. I review complex layout concepts, tool schematics, and product designs through the lens of a front-line engineer to ensure they are fully optimized for real-world manufacturability, flawless yield, and zero-defect compliance
• Tooling Engineer Carsem Sdn. Bhd. · Full-time Mar 1997 – Mar 2015 18 yrs Ipoh, Perak, Malaysia Tooling Design Engineer (Mold, Trim/Form & Singulation)
  
  Tooling Business Unit operates as a vital, centralized supporting BU across the entire company, delivering precision engineering solutions to all manufacturing lines. As a Tooling Design Engineer, I am responsible for the end-to-end design architectures of the critical backend assembly processes: Mold, Trim & Form (T&F), and Singulation.
  
  Key Design Responsibilities includes:
  
  1. High-Precision Mold Design
  Worked with suppliers to architect and optimize complex mold tool configurations, including mold chases, cavities, runners, gates, and venting systems for transfer molding.
  Utilize advanced 2D drafting and 3D modeling tools to ensure total geometric accuracy of mold inserts, minimizing compound bleed, flashing, and package voiding.
  
  2. Trim & Form (T&F) Progressive Tooling Design
  Design high-precision punch and die matrices for trim and form systems, managing tighter clearances for ultra-fine-pitch leadframes.
