PCB Assembly FAQ
After inspecting your Bill of Material, we transmit to the customer the parts we currently have in stock, which are usually low cost or free components. Our procurement team will give you suggestions regarding how to obtain cost savings in sourcing cross-referenced parts. This service is only advisory. The customer always makes the final decision.
If we do not have inventory in stock, we order parts in volume per your Bill of Materials (BOM) so you obtain the highest level of cost savings. For hard-to-find or rarely used parts, we typically add 5% as spare parts to insure we have enough parts to manufacture your complete order. For order minimums, we contact the customer for approvals.
Total lead time includes part sourcing plus assembly lead time. We try to compress the total lead time by using our resources to accomplish work in a timely fashion. Once he have received your Gerber file and Bill of Material, we begin procuring your parts and preparing the stencil.
As a general rule, we have no minimum order size. However, larger orders obtain greater cost savings.
We can maintain extra parts in stock to be used on future orders. But if you want the parts for your own testing, we can send them to you at no charge. Contact us about the extra parts when your PCBs are ready for shipment.
