As we all know, the semiconductor industry is highly precise. Therefore, the craftsmanship of its suppliers must also meet a high standard. For many years, BLIKSEN has been a partner of several major semiconductor companies, assisting in the production of related components.
We continuously push our limits, advancing our sheet metal processing techniques to keep pace with our clients' needs. But how precise do semiconductor parts need to be to meet industry standards?
And how does BLIKSEN achieve this level of precision? This article will take you through the details!

Tolerance Standards for Semiconductor Sheet Metal Parts
Semiconductor precision parts come in various types, including metal, plastic, and electrical distribution components. In sheet metal processing, some parts demand extremely high precision, with tolerances measured in micrometers (µm) (1 µm = 0.001 mm). While some parts may not require such extreme precision, they are still considered highly refined by traditional industry standards.
For example, in general sheet metal processing, where relatively simple procedures like laser cutting and robotic bending are used, a tolerance of 1 mm is already considered a mark of exceptional craftsmanship. However, semiconductor manufacturing equipment typically requires a tolerance of within 0.2 mm. Currently, BLIKSEN is working on achieving a consistent tolerance of less than 0.1 mm, a goal we aim to realize shortly.
That said, if customers have specific requirements and the budget allows, we can further refine sheet metal parts by sending them for CNC processing, achieving even tighter tolerances. Everything depends on the customer’s needs. We tailor our services to meet each customer's specific requirements.

Essential Conditions for Achieving Precision Standards
Reaching the level of craftsmanship mentioned above is not an overnight task. Both equipment and in-house personnel must meet certain conditions to achieve it.
Over the years, BLIKSEN has actively strengthened and improved the following aspects to keep up with global trends and the fast pace of our clients.
Equipment Requirements
- Procure laser equipment with an accuracy of 0.1mm to prevent the accumulation of tolerance errors.
- Select bending machines with an accuracy of 0.003mm, placing special emphasis on the backgauge and stopper system functionality, as these are crucial for the bending angles of the final product. The more precise the positioning, the better.
- Introduce a "bending simulation system" to simulate bending sequences and tooling in advance, reducing errors during the process and ensuring precision.
- Establish standard operating procedures for welding, including current and voltage settings, welding methods, and the use of fixtures, to control welding deformation.
- Install 3D measurement equipment to verify if products are within tolerance.
- If the product is uncommon or has special requirements that cannot be inspected in-house, it will be sent to a third-party institution for inspection.
Professional Requirements for Personnel
- Establishing a Development Department: In the past, BLIKSEN did not allocate personnel to focus on technological research. To keep up with clients’ needs, a development department was later established, driving continuous technical progress.
- Meticulous Bending Machine Operators: Operators must conduct comprehensive checks, including verifying the drawings, bending tools, workpieces, direction, angle, positioning, and sequence. Every step is crucial.
- Welding Procedure Specification (WPS): Before starting a project, review the engineering drawings, and prepare a Welding Procedure Specification (WPS) that details the welding methods, materials, dimensions, temperature, current, and gas to be used. This ensures that https://www.bliksen.com/wp-admin/post.php?post=16771&action=edit&lang=en#different welders can follow the guidelines and produce consistent, high-quality welds.
- Pursuit of Excellence: As the semiconductor industry is one of the most advanced sectors globally, it often demands cutting-edge techniques. To grow together with this industry, it is essential to learn and explore new manufacturing processes. Embracing challenges, investing in equipment, and training professional personnel are key to avoiding obsolescence and staying ahead in technology.
Sheet metal components for semiconductor equipment require strict process control, including the final inspection. Completing inspection and packaging inside a cleanroom ensures that the dust levels meet customer specifications.
A Decade of Craftsmanship: Delivering High-Precision Components
BLIKSEN’s ability to deliver products that meet high craftsmanship standards is the result of a decade-long commitment. Ten years ago, we took a bold step by heavily investing in advanced equipment and professional training for our staff.
Our technical capabilities further improved six years ago when we started manufacturing large display products.
It is truly thanks to the guidance and support of our clients along the way that BLIKSEN has been able to continuously refine its processes, and become proficient in new product development, first-article inspection, and mass production.
We have mastered the inspection phases and perform processing and assembly in clean environments, continuing to offer our clients the best possible service and experience.
With an unwavering spirit to overcome difficulties and challenges, BLIKSEN has cultivated deep expertise in the semiconductor field for over 10 years, gaining extensive experience in professional sheet metal design and development, sheet metal processing techniques, and product management.
