Contract Assembly - Quote

  • What information I need to give you so that you can quote my PCB assembly requirement? You need to provide us with:

    PCB design files e.g. gerbers, NC drill data, technical specification etc.
    BOM (Bill of Material) – Please include manufacturer's name and manufacturer's part numbers
    Assembly drawings or picture of already assembled boards, if any.
    Detail about any special assembly requirements
    List of components, if you are going to supply
  • How long does a PCB assembly quote take to prepare? 2 working days, provided there is no query from our component procurement and PCB assembly team.

    If we have query regarding your part or its availability or if we have any other assembly related doubts, we may take extra time to quote. In any case, we will be in touch with you throughout the quote process.
  • What should I include in a BOM (Bill of Material)? Any BOM should, ideally, have the following information:

    Reference designators
    Part names
    Manufacturer’s name and part number
    Vendor name (e.g. Digikey, Mouser, element14 etc.)
    Vendor part number
    Part Quantity
    Any other information
  • Why do you need the silk screen gerber layer for assembly? The silkscreen layer normally includes POLARITY information and reference designators for parts. From diodes and polarized capacitors to QFNs and BGAs, orientation is critical. If your CAD system is 'weak' in calling out the rotation, then the visible information contained in the silk is our best check.

    You may also provide part locations in other formats like pdf file, assembly drawings or picture files. However, actual silk screen layer in gerber is always preferable.

PCB Design Tips

When designing a PCB, try to limit the amount of draws you use. Draws use a lot of memory and slow the programming time. Use a flash for pads instead.
