Team spirit in the implementation and execution of engineering projects.

　　Since April 9 last year, I have been part of the Pulinn family for one year, primarily responsible for ERP configuration at Factory No. 2, establishing production workflows, and handling documentation, internal audits, and change management. Although my daily tasks can be tedious, completing each new product brings a genuine sense of accomplishment. When I first joined Pulinn, I knew nothing about PCB manufacturing. I felt a mix of nervousness and excitement about my future role, along with some apprehension—worrying whether I could rise to the challenge. Fortunately, Pulinn gave me this opportunity: through a two-month on‑line internship, I gained an in-depth understanding of the PCB production process and learned what information each department needs to input into the ERP system to carry out their work. This experience has been immensely helpful for my subsequent duties. After finishing my line‑side internship, I moved to the Engineering Department and began working on preliminary setup. This phase requires a thorough grasp of customer specifications and, based on those specs, customer documents, and raw data, identifying the product’s unique characteristics to assess whether they align with our manufacturing capabilities. Any special requirements are clearly noted on the customer‑specific process sheet, providing clear guidance to CAT personnel and facilitating both ERP configuration and review.
　　As a preliminary design engineer, I am keenly aware of the critical importance of my work, as the accuracy of early-stage specifications directly impacts the product’s yield rate. To excel in this role, one must possess strong technical expertise and, based on a thorough understanding of each process’s capabilities, evaluate customer orders to determine feasibility. When a specification falls outside the acceptable range, proactively communicate with the customer and, where feasible and without compromising performance, seek ways to accommodate the deviation. Additionally, identify customer standards and the product’s unique characteristics; verify alignment between customer requirements and engineering drawings, and seek clarification from the customer if discrepancies arise. Determine the appropriate material grade and dimensions to maximize sheet utilization and minimize costs. Specify the laminate structure and type of prepreg, adhering to customer‑specified requirements when provided. Select the forming method—milling, V‑forming, or stamping—and calculate production quantities based on the product’s process requirements, special features, and manufacturing complexity. Finally, develop an ERP‑based production workflow tailored to the product’s attributes, ensuring it is both scientifically sound and operationally efficient, while clearly documenting any customer‑specific requirements in the relevant process notes. In summary, the primary objective of a preliminary design engineer is to identify customers’ unique needs for new products, optimize the production flow, and, within the constraints of our facility’s capabilities and cost‑reduction goals, deliver products that meet customer expectations.
　　As the ancients said, “When hearts are united, even Mount Tai can be moved.” Through my work in the Engineering Department, I’ve come to realize that a team’s success or failure depends on each and every one of us. Under Manager Yan’s leadership, everyone is striving to uphold the team’s honor. We hold weekly meetings to review each member’s performance from the previous week, particularly discussing areas for improvement. This allows everyone to clearly identify their own shortcomings and prevent recurring mistakes—providing an excellent opportunity for new team members to grow. When challenges arise, our senior colleagues patiently guide us until we fully understand. Thanks to everyone’s collective efforts, the Engineering Department has not only enhanced its technical expertise and production capacity but also reduced error rates and eliminated large‑scale scrap. As a member of this team—and as part of Pulinn—I feel immense pride. Let us join forces to make Pulinn’s future even brighter!
