In order to satisfy every combination of assembly profile, material use and application requirement, we offer the following comprehensive range of solderable finishes as in-house processes:
- Traditional lead based HASL (military & life critical applications predominantly)
- Lead-free HASL
- Immersion Tin (Sn)
- Immersion Silver (Ag)
- Immersion Gold over Nickel (ENIG)
- Electrolytic Gold over Nickel (ENEG)
- Gold over Palladium
- OSP (Organic Solderability Preservative)
We are happy to advise you on the most suitable finish based on a number of factors including shelf life, handing considerations, surface topography, assembly open windows between processes and obviously cost.
All boards supplied include a comprehensive quality report that specifies the plating specifications of the boards along with a cross section if required that illustrates inner layer plating depths for the through hole plating and surface treatments.
Momentum also offer a wide range of solder resist colours and finishes (gloss or matte)to suit your design requirements.
Whilst the vast majority of PCBs are manufactured in industry-standard green, we also offer red, blue, yellow, clear and brilliant white and black resists that are extensively used in the manufacture of LED-based lighting applications to either reflect or suppress peripheral light.
All of the above colours are offered without a cost premium and the inks utilised have been standardised to offer the highest levels of colour fastness and resistance to fade and/or discolouration when processed.
We are happy to advise you on the best use of materials and finish as part of our service.
