Material Selection

Material selection involves the identification, detailed description, and designation of materials critical to a product design.

Material selection affects the cost and performance of a connector and includes metals, polymers, and associated materials. Frequently, more than one material can meet application requirements. Metal selection encompasses the physical properties, conductivity, standard sizing, finishing requirements, handling, and cost. Polymer selection considers the product design, temperature capability, flammability, fillers, colorants, flow, and economics. Associated materials (plating, solders, sealants, adhesives and lubricants) depend on the adjoining materials and the end-use environment.

WHY APEX:

• Employ a broad materials knowledge base
• Gain familiarity with suppliers and availability options
• Obtain experience in optimizing cost/benefit ratios
• Draw on ability to identify rare or special-use materials

APEX MATERIAL SELECTION PROVIDES:

• Optimized mechanical, electrical, and physical properties
• Production cost estimates
• Environmental and chemical compatibility
• Manufacturing and process capabilities
• Sourcing location and supplier availability
• Standardization on common sizes and readily available selections

EXAMPLES OF APEX MATERIAL SELECTION:

• Recommended finish specifications to enhance durability
• Suggested a sealant for an outdoor connector application
• Specified a high temperature plastic for a light pipe
• Recommended an alternative alloy to eliminate plating
• Identified polymers capable of lead-free re-flow temperatures
• Developed a surface treatment to reduce gold usage
• Replaced a metal component with polymer in a medical device
• Eliminated lead use by recommending solder/flux alternatives
