When producing female header connectors, we often use plastic materials. The commonly used plastic materials are PBT, 6T, 9T, and LCP. Do you know the difference between these four plastic materials? Next, LCSC electronics supplier CJT connector will analyze and explain each material’s quality, temperature resistance, and price. Let’s learn together.
PBT Plastic Material
We often use PBT plastic to produce 2.54 pitch 180-degree/90-degree headers. Its welding temperature resistance is limited to about 200 degrees. Despite its low cost and high strength, it is vital to consider alternative materials for applications with higher temperature requirements. However, this material has poor formability and severe shrinkage. Additionally, due to its low melting temperature, it may melt during wave soldering.
6T Plastic Material
This material is typically used for 2.54-pitch chip headers and 1.27-pitch/2.0-pitch series headers. Since the resistance to welding temperature is 260 degrees and the maximum instantaneous temperature can reach 290 degrees, the cost of female connectors produced using this material is slightly higher. The choice of this material is generally due to the quality requirements of customers.
9T Plastic Material
This material is similar to 6T plastic material. We generally use it in 2.54-pitch chip headers and 1.27-pitch/2.0-pitch series headers. The resistance to welding temperature is 260 degrees, and the maximum instantaneous temperature can reach 300 degrees. Since this material is expensive, we use 9T plastic to produce connector products when customers have special needs.
LCP Plastic Material
LCP plastic is suitable for producing female connector of various spacing series. The LCP plastic has a welding temperature resistance of 260 degrees and can reach the highest 320 degrees instantaneous temperature. Because the material used has a small coefficient of linear expansion. Injection molding has low shrinkage, outstanding strength, elastic modulus, and excellent heat resistance. It has a high load deformation temperature, so some can be as high as 340 degrees or more. LCP also has excellent chemical resistance and air tightness, so generally, LCP materials are the first choice for connectors that require SMT. Due to its high cost, this material is typically only utilized by customers with specific requirements.
Regarding the plastic materials used for female header connector, there are four types of plastic: PBT, 6T, 9T, and LCP. We will decide which one to use based on the customer’s needs. It mainly depends on whether the customer’s product has quality requirements for the material.
