[Avoiding Metal Contamination in Semiconductor Cleaning Processes] Resin Screw Selection and CHEMIS's Strengths

Semiconductor manufacturing involves chemical cleaning at many stages — slicing, polishing, film deposition, resist coating, and etching of silicon wafers. The chemicals used are wide-ranging, including hydrofluoric acid, hydrochloric acid, sulfuric acid, potassium hydroxide, and ammonia solution, r ...

How Much Dimensional Change from Moisture Absorption Can PA Screws Tolerate? PC Screws as an Alternative

When selecting resin screws, it's important to consider not only strength and heat resistance, but also how dimensions and mechanical properties change with temperature and humidity. PA in particular has a relatively high water absorption rate, and depending on the operating environment, moisture ab ...

[PEEK Screws M2-M12] Replacing Metal Screws to Prevent Salt-Induced Corrosion and Reduce Total Cost

Thailand's plants face high humidity and salt exposure year-round, driving up maintenance costs through corrosion of metal parts. This article outlines how replacing metal screws with PEEK (Polyether Ether Ketone) screws — rated for continuous use up to 240°C — can address corrosion and reduce total ...

【ASEAN Plastic Screw Supply Network】Supplying Stock to Vietnam, Malaysia, and Singapore from a Thailand Hub

As manufacturing equipment across ASEAN becomes more advanced, non-metal options such as electrical insulation and weight reduction are increasingly in demand. However, specialty plastic screws are often hard to source locally, and importing from Japan can cause delivery delays that become a bottlen ...

Plastic Screw Insulation Standards: Preventing Short Circuits and Optimizing Thermal Management in Electronic Devices

In Thailand's hot and humid environment, increasing component density raises the risk of short circuits on PCBs, and metal screws can make it harder to maintain required insulation clearance. This article outlines how plastic screws, with their electrical insulation and low thermal conductivity, can ...
