LPO compared to Conformal Coating

“Conformal Coating protects an electronic assembly like a matador’s cape stops a bull.” - Scott Reisfield - Chief Marketing Officer, LMI

LPO bonds to the electronic assembly, like conformal coating. LPO offers more substantial physical protection and guards against dust, water and vibration.

  • Eliminates the need for housings.
  • Long lasting PCB protection. Say goodbye to corrosion, whiskers and cracking.
  • No silicone migration.
  • No UV cure lamps.
  • Reduces work in process and safety stock requirements.
  • No liquid dunnage.

For virtually the same cost as conformal coating and much less than UV cure, get protection you can count on from LPO.

Sources of Failure in Conformal Coating
Failure issue Conformal Coating LPO
Vibration and shock Offers no additional protection against vibration and shock. Components can fall off of assembly. Helps to bond components to the assembly. Failure due to vibration and shock significantly reduced.
Dust Dust build up on assembly can lead to shorts. Dust does not build up on assembly, so dust does not cause board level shorts.
Impurities Impurities introduced during production remain on assembly and can lead to corrosion over time. LPO process flushes impurities off of assembly, leading to virtually no corrosion.
Heat Housing traps air around assembly, which may lead to heat related failures. LPO material is thermally conductive. Improved heat dissipation.
Cure Air cure for approximately one hour or UV cure under lights. No cure time.
