BOM - Bill Of Material

What is a BOM?

BOM - Bill of Material is a list of all the components to be soldered on the PCB.

MPN - Manufacturer Part Number

DNP - Do Not Populate


Blank MPN

Our system will give a warning if a BOM is uploaded with a blank MPN field and may ask you to enter all the accurate details and upload the file again.

DNP - Do Not Populate

We understand if you would not want a chip to be populated, please mention “DNP” (Do not Populate) in the MPN column of the BOM to highlight this.

Quantity as Zero

If your BOM has 0 in the Quantity field, it will be treated as DNP (Do Not Populate).

Format of the Bill of Material (BOM)

Where do I find MPN (Manufacturer Part Number)?

The key to deliver an error free BOM is the correct MPN details. Access the below catalogue of electronic component distributors (Third Party) to capture the MPN or look it up on the datasheet provided by the manufacturer.

Placement Files

Partial Services

(PCB manufacturing/assembly)

Currently, we only cater to turnkey projects that establish end to end process. To optimize your deliverables, we would be unable to offer just PCB manufacturing or assembly services. However, if you need spare components for your project, just add it to the BOM and we will ship it to you.

Delivery Schedules

Estimate Dispatch date will be provided when the order is placed successfully, assuming we don’t need to contact you for any clarifications after running manufacturing checks on your files.

However, there could be unexpected delays due to one or more of the following reasons:

  • Components are out of stock
  • BOM did not pass the Quality check
  • Stuck in Customs due to commercial reasons

We will notify you by email if there are any delays due to unforeseen circumstances.


Free Shipping for you!


Our Payment gateway offers a variety of electronic payment options for you to choose from.

Order Cancellation

Unfortunately, we do not allow order cancellation because our supply chain is setup to process incoming orders immediately in order to give you the quickest service.

However, if you file a ticket against the order we might be able to pause the manufacturing process for you to make changes to the design files. You may have to pay the difference post the evaluation of the changes.


Make sure that and are whitelisted from your SPAM filters.
