We offer the full range of in-house solderable finishes including HASL, lead-free HASL, immersion gold, immersion silver, immersion tin or OSP.
All PCB finishes are applied in accordance with IPC to offer the maximum shelf life and optimised solderability across a wide range of assembly process profiles.
When a PCB is designed for a specific application, a number of factors need to be considered to offer you the very best assembly performance, manufacturing yield and long-term reliability.
One area where we can offer you considerable guidance and expertise is in selecting the most appropriate solderable finish to match your assembly method and equipment. The topography or flatness of the solderable finish will allow small surface mounted components to be more accurately placed for example, and here we would recommend the use of an immersion finish such as ENiG (Electroless nickel, immersion gold).
However, for conventional technologies using through-hole components or larger surface mounted components, a lead-free HASL finish might be better matched to the consumables being used within the assembly process.
There are many factors to consider when choosing a specific solderable finish. Aesthetics can often play a large part in the choice made, such as a gold finish on products where the circuitry might be visible on the finished item. Other factors may include matching the solderable finish specifically to the temperature, component choice or use of consumables selected to populate the board.
Shelf-life, aesthetics, resistance to handling, solderability and the temperature required to successfully assemble a board will all come into play, and our engineering team can give you the best advice.”
Quite often, some finishes are specified on the submitted Gerber files and/or engineering drawings that are not always the best match for your assembly line or assembly partner. We will therefore recommend options to you that maximise efficiency, guarantee the best solder joints, storage and operational life for the product.
Our consultative service is free and can be carried out as part of an NPI or a change of assembly process.
