Chemical etching electronic components


Published on

The chemical etching process is ideal for precision metal components in many industries electronic systems such as aerospace, medical, R/F Microwave, electronics, automotive and more. Metal parts are burr-free, and the properties remain unchanged. There is no thermal stress along the surface or edges. Complex designs are manufactured to precision and more economical than stamping and laser cutting. The low-cost digital tooling makes prototype changes easy to modify. The photo etching process is capable of etching a variety of metals, such as copper, phosphorous bronze, brass, nickel/silver, and steel.

Chemical etching electronic components

  1. 1. 5 Reasons Why Chemical Etching Is Ideal For Electronic Components
  2. 2. 1. Variety of Metal Etching Capabilities - Copper - Beryllium Copper - Phosphorous Bronze - Brass - Nickel/Silver - Steel/Stainless Steel
  3. 3. Copper Beryllium Copper • High electrical conductivity • Good thermal conductivity • Solderability • Strength • Corrosion resistant (post plating enhances corrosion resistance) • Highly conductive • Strongest of the copper alloys • Easy to form and retain shapes
  4. 4. Common Applications: EMI/RFI shielding Contacts Pins Terminals Connectors Springs Bus bars
  5. 5. Brass •Copper and zinc alloy •High electrical conductivity •Good thermal conductivity •Strength •Corrosion resistant •Highly workable metal/ good for forming and shape retention
  6. 6. Common Application s: Springs Contacts Connectors Lead frames Bus bars
  7. 7. Phosphorous Bronze •Bronze alloy containing copper and zinc •Superior spring qualities •High fatigue resistance •Excellent formability •High corrosion resistance
  8. 8. Common application s: Battery Contacts Springs
  9. 9. Nickel/Silver •Alloy made of copper, nickel, and zinc •High corrosion resistance •Excellent solderability •Hard, malleable, ductile •Nonmagnetic
  10. 10. Common application s: EMI/RFI shielding
  11. 11. Steel (Cold Rolled) Stainless Steel • High strength • Formability • Spring properties • Shape retention • The addition of tin plating makes it highly conductive and solderable • Highly resistant to moisture- related corrosion • Excellent thermal conductivity
  12. 12. Common application s: EMI/RFI shielding Filters Flat springs
  13. 13. 2. Resistant To Thermal Stress   • No thermal stress and deformations • Metal properties remain unaffected • No localized point of contact from heat or gas • Smooth surface and edges
  14. 14. 3. Metals Remain Burr-Free •Smooth surfaces, and precision edges •No need for costly secondary deburring operations •Eliminates surface friction between mating components
  15. 15. 4. Thin Materials With Complex Designs •Can etch thin metal parts with low tolerances and smaller dimensions •Complex features such as holes and slots are etched simultaneously and quicker than laser cutting and wire EDM •Cost-effective and saves time
  16. 16. 5. Easy To Modify Prototyping • Low-cost, flexible digital tooling • Easy to make revisions • More than one prototype can be etched on the sheet if material and thickness are the same • AME Parts Now program can deliver prototypes in 24-48 hours for most parts
