Among the key subjects on The difference between HASL VS ENIG include:

1.HASL: This section provides a brief overview of the definition, function, and benefits of hot air solder balance.

2.ENIG: This section introduces ENIG mainly through three aspects: Definition, ENIG finish, ENIG plating.

3.HASL VS ENIG: This section focuses on the advantages and disadvantages of HASL and ENIG.

3.1 The benefits of HASL are:

  • easy to use
  • low cost
  • Long storage life
  • Good surface finish
  •  Ensure that copper does not oxidise
  • Continuous to maintain wetting
  •  Visual inspection of surface finish

3.2 The disadvantages of HASL are:

  • Not applicable to surface mount technology surface
  • Not suitable for fine pitch
  • Not ideal for manufacturing
  • Due to high heat exposure in the process, there may be some disadvantages
  • Unable to withstand the tight tolerances of plated holes
  • Hot air solder flat is not suitable for wire bonding
  • When using this surface treatment, the plated through holes may be broken due to high temperature

3.3 ENIG advantages:

  • Ideal for surface treatment of plated through holes, good storage life, It has no lead,
  • Ideal for use as bottom metal for cob wiring, excellent electrical conductivity,
  • Has the ability to prevent oxidation

3.4 ENIG’s shortcomings: expensive, non-reusable,

  •  Electroless nickel immersion gold is associated with signal loss, NIG’s process is complex,
  • And black liners are prone to occur due to its low volatilisation strength.

4. Other surface treatment processes:

This section is from the following five aspects:

Organic Solderability Protection (OSP), Hard Electrolytic Gold, Dip Tin, Impregnated Silver, Nickel Palladium (ENEPIG), their advantages and disadvantages provide in-depth information on other surface treatment processes.
