Mar 23, 2026
1. Core Characteristics of PEEK Gears
PEEK (Polyether Ether Ketone) is a special engineering plastic with excellent comprehensive performance. Its molecular structure contains stable benzene rings and ether bonds, endowing it with core characteristics adapted to the complex working conditions of PCB equipment. The details are as follows, and compared with traditional gear materials to highlight its application advantages:
High temperature resistance: The continuous service temperature can reach 260℃, and the short-term temperature resistance exceeds 300℃, which can adapt to the high-temperature operating environment (equipment working temperature is usually 80-150℃) of the desmearing and electroplating processes of PCB equipment without softening or deformation. It is far superior to POM (temperature resistance ≤100℃), PA (temperature resistance ≤120℃) and ordinary metal gears (easy to oxidize at high temperature);
Chemical corrosion resistance: It has excellent corrosion resistance to chemical media commonly used in PCB equipment, such as electroplating solution, desmearing agent and cleaning agent (such as Circubond 2200 series brown oxide, PCM PLUS electroplating solution), without swelling, cracking or performance attenuation, solving the pain points that traditional metal gears are easy to rust and ordinary plastic gears are easy to be eroded by chemical media;
High rigidity and precision: The tensile strength can reach more than 100MPa, and the rigidity is close to that of metal. After precision CNC machining, the tolerance can be controlled within ±0.01mm, which fully matches the requirements of PCB equipment for transmission precision (the precision requirement of PCB board transmission, etching and other processes is ≤±0.02mm), and there is no offset or jitter during operation;
Self-lubrication and low wear: The friction coefficient is low (about 0.15-0.2 when rubbing against steel), and it can operate stably without additional lubrication, reducing friction loss during gear meshing. The wear rate is only 1/10 of that of traditional metal gears, and the service life is increased by 3-5 times. At the same time, it avoids lubricating oil leakage polluting the PCB board;
Light weight and low noise: The density is only 1.32g/cm³, less than 1/5 of that of steel gears, which can reduce the operating load of the transmission system of PCB equipment and reduce energy consumption; at the same time, it has excellent damping characteristics, and the operating noise is 15-20dB lower than that of metal gears, adapting to the low noise requirements of the PCB manufacturing workshop.

With years of experience in PEEK precision processing, Guangzhou Best Rubber & Plastic provides customized PEEK gear services for PCB equipment for many domestic PCB manufacturing enterprises. The following are 2 typical implementation cases, covering the core PCB equipment models, detailing the application scenarios, pain point solutions and application effects:
Case 1: ATOTECH Uniplate® P Desmearing Equipment - Application of PEEK Transmission Gears
【Equipment Working Conditions】Uniplate® P is an efficient PCB desmearing equipment, widely used in the desmearing process of HDI boards and multi-layer boards. When the equipment is running, the transmission gear needs to drive the PCB board to be continuously transported, in a complex environment of high temperature (100-120℃) and desmearing agent (alkaline medium). The gear needs to run at high frequency (rotating speed 300-500r/min), and at the same time ensure the transmission precision of the PCB board to avoid offset and scratch.
【Original Pain Points】The customer previously used stainless steel gears, and obvious problems appeared after 3 months of use: ① Stainless steel gears are easy to rust in the desmearing agent medium, and rust debris falls off to pollute the PCB board, resulting in a 5%-8% decrease in product yield; ② The meshing part of the gear needs to be regularly added with lubricating oil, and the leakage of lubricating oil mixed with the desmearing agent affects the desmearing effect and increases the frequency of equipment maintenance; ③ Under high-frequency operation, the gear wears seriously and needs to be replaced every 3 months, with high maintenance costs.
【PEEK Gear Customization Scheme】According to the working condition requirements of the equipment, Guangzhou Best customized PEEK transmission gears suitable for Uniplate® P equipment, with specific optimizations as follows: ① High-quality pure PEEK raw materials are selected, combined with glass fiber modification to enhance the rigidity and wear resistance of the gear, adapting to the high-frequency operation requirements; ② Precision processing is carried out according to the original equipment drawings, and the tolerance is controlled within ±0.01mm to ensure perfect adaptation to the equipment transmission system and avoid transmission offset; ③ Optimize the gear tooth profile design, adopt involute tooth profile to reduce meshing friction and lower operating noise; ④ The gear surface is polished to avoid burrs scratching the PCB board and improve the resistance to chemical medium erosion.
【Application Effect】After the PEEK gear is put into use, the original pain points are completely solved: ① No rust and no debris falling off, the PCB product yield is increased to more than 99%; ② The self-lubricating feature eliminates the need for adding lubricating oil, reduces the frequency of equipment maintenance, and shortens the monthly maintenance time by 60%; ③ The service life is extended to more than 18 months, the replacement frequency is reduced by 80%, and the annual cost of gear replacement and maintenance can be saved by about 25,000 yuan; ④ The operating noise is reduced from 75dB to 55dB, optimizing the workshop operating environment, and fully adapting to the long-term stable operation needs of Uniplate® P equipment.
Case 2: ATOTECH P-Line Electroplating Equipment - Application of PEEK Guide Gears
【Equipment Working Conditions】P-Line is a high-performance PCB electroplating equipment, mainly used for the metallization electroplating process of PCB boards. When the equipment is running, the guide gear is responsible for accurately controlling the transmission speed of the PCB board (0.5-3.5m/min) to ensure uniform electroplating of the PCB board. The gear needs to be in long-term contact with the electroplating solution (acid medium), and at the same time bear a certain load, requiring extremely high dimensional stability and corrosion resistance.
【Original Pain Points】The customer previously used PVDF gears, and obvious problems appeared after 6 months of use: ① PVDF gears have insufficient rigidity, and deformation occurs after long-term load bearing, leading to PCB board transmission offset, uneven electroplating thickness, and increased product defect rate; ② Although it has a certain corrosion resistance, under the high-temperature electroplating environment (110-130℃), the dimensional change rate exceeds 0.1%, and the precision attenuates seriously; ③ The gear tooth surface wears too fast, and tooth surface shedding is easy to occur, affecting the normal operation of the equipment.
【PEEK Gear Customization Scheme】To address the pain points of the equipment, Guangzhou Best customized special PEEK guide gears, with the scheme as follows: ① Modified PEEK raw materials (added with carbon fiber reinforcement) are used to improve the rigidity and dimensional stability of the gear, and the dimensional change rate is controlled within 0.05%; ② Precisely match the guide mechanism of P-Line equipment, optimize the gear installation precision, and ensure no offset of PCB board transmission; ③ The gear tooth surface is treated with special wear resistance to improve meshing wear resistance and adapt to long-term high-frequency operation; ④ Strictly control the raw material purity to ensure no harmful substances precipitate from the gear, meeting the environmental protection requirements of the PCB electroplating process.
【Application Effect】After the PEEK guide gear is put into use, the application effect is remarkable: ① Excellent dimensional stability, no deformation and no precision attenuation, the uniformity of PCB board electroplating thickness is increased to ±0.005mm, and the product defect rate is reduced to less than 1%; ② Outstanding corrosion resistance to electroplating solution, no swelling or cracking after 24 months of use, and the service life is 4 times that of PVDF gears; ③ The gear runs stably without tooth surface shedding, the equipment failure rate is reduced by 90%, the production efficiency is greatly improved, and it has been highly recognized by customers.
3. Notes on the Application of PEEK Gears in PCB Equipment
To ensure that PEEK gears play the best performance in PCB equipment, combined with practical application experience, the following notes are summarized for industry reference:
Raw material selection: According to the specific working conditions (temperature, medium, load) of PCB equipment, select appropriate PEEK raw materials. For example, glass fiber/carbon fiber modified PEEK can be selected for high temperature and high load working conditions, and pure PEEK raw materials can be selected for complex chemical medium working conditions to ensure performance adaptation;
Processing precision: PCB equipment has extremely high requirements on gear precision. High-precision CNC equipment should be used during processing to strictly control the tolerance (it is recommended to be ≤±0.01mm). At the same time, optimize the tooth profile design to reduce meshing friction and avoid affecting the equipment transmission precision;
Installation and commissioning: During installation, ensure that the PEEK gear is accurately connected with the equipment transmission system to avoid accelerated gear wear or precision degradation caused by installation deviation; during commissioning, control the gear running speed and load to avoid overload operation;
Daily maintenance: There is no need to add lubricating oil regularly, only need to regularly clean the dust and chemical medium residues on the gear surface to avoid impurities affecting gear meshing; if the gear is found to be worn, deformed and other problems, it should be replaced in time to ensure the normal operation of the equipment.
