PCB Assembly FAQ:

How does SI Electronics handle part cross-referencing or replacements on turnkey PCB assembly orders?

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.
 
For turnkey assembly orders, what is the process by which SI Electronics procures components?
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.
 
What are your turnkey lead times?
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.
 
What is the minimum size for turnkey assembly orders?
As a general rule, we have no minimum order size. However, larger orders obtain greater cost savings.
 
What do you do with extra parts not used in the turnkey PCB assembly process?
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.
 
What information do I need to provide to initiate a turnkey PCB assembly order?
  • Gerber file(s)
  • Bill of Material (BOM) in Microsoft excel (.xls) format that includes the vendors’ names, part numbers, ref designators, detailed part description and amount needed.
  • Centroid data file
  • Other specifications or instructions as needed.
 
What is included in a Centroid data file?
Created by a CAD system, a Centroid data file is a machine file that details the X, Y, side, top, bottom and rotation locations, as well as the reference designator that is used in PCB prototype fabrication and assembly.
 
Is SI capable of manufacturing lead free PCB Assembly?
Yes. SI’s production facilities has two additional assembly areas dedicated to lead free assembly.
 
Does SI perform x-ray inspection of Ball Grid Arrays?
Yes. We perform x-ray inspections of BGAs. In addition, SI is capable of conducting x-ray inspection lead-less IC pins and other micro-sized components with leads too small to be viewed with a microscope.
 
Can SI Electronics perform partial PCB assembly?
Yes. When you place a turnkey PCB assembly order, please make it know to our order entry team what components you prefer not to be assembled and ensure this preference is annotated in your bill of materials.
 
For multiple orders, how does SI prefer parts to be kitted?
  • Place multiple kits in one shipping package with each order labeled by the appropriate order number.
  • Shared parts should be marked by a label to indicate their common use.
  • Increase the extra parts quantity by 5 percent for each separate order.
 
How do I need to label and package parts?
  • Label with the part number and reference designators per your BOM each tray, bag or container.
  • Parts that require special storage requirements such as static or moister should be packaged appropriately.
  • Seal or tape tightly all SMT parts. Loose parts can be damaged and can delay the production process.

What is SI’s shipping address?
Please label each package with your purchase-order number. Ship to:
