SMT Manufacturing Capability

1: On turn-key PCBA project, what does JPT do about part crossing or substitutions?
First of all, we check your Bill of Materials (BOM), and send you BOM with the brand we chose for each component and also we will mark the components in different color to tell youwhich components we chose the substitutions. We will give you advice on how to reduce BOM costs by parts crossing or substitutions, but all part changes are your own final decision.
2: How do you order components for Turn-Key orders?
We usually order 3‰ or 5 spare parts (depending on size and cost) to accomplish your order without missing parts or shortages due to Production Loss. If we encounter any Issues With BOM Components, such as a large minimum order for a certain part, we will communicate with you to find the best solution.
3: What is the lead time on a turn-key order?
The overall project Lead Time is the sum Parts Procurement lead time and PCB Assembly lead time. However, we try to shorten the time line by streamlining our PCB Assembly Process. For instance, once we receive your Gerber Files for PCB Fabrication and BOM for PCB Assembly, we will start to prepare the stencil for your board and complete the fabrication concurrently with the parts procurement process.
4: Is there a minimum order size for turn-key orders?
No. We have no restrictions on your order size; however, larger orders are more cost effective. We can work with you to find a good solution for your specific needs in cost reduction.
5: What happens to the leftover components on Turn-Key orders?
We can keep your leftover parts in our inventory for your next order if you think these parts will be used again; otherwise, we can ship spare parts with your completed order so you have access to them for troubleshooting and repairs.
6: What do I need to send for a turn-key order?
* Bill of Materials, complete information in excel format. This document should include manufacturer names, part numbers, Reference Designators, component descriptions, and quantities.
* Gerber Files
* Centroid Data (AKA Pick and Place or XY-Coordinate Data)
* Other requirements or assembly instructions if applicable
7: Can you handle lead-free builds?
Yes, we have 12 lines for Lead-Free PCB Assembly.
8: Do you X-ray BGAs?
Yes. We also use X-Ray Inspection for any lead-less IC pins and other parts that have leads which cannot be seen with a
microscope.
9: How do I need to supply my components?
* Each bag, tray, etc. should be clearly marked with the part number, reference designators that is listed on your bill of
materials.
* Components which are sensitive to moisture or static must be packaged in compliance with their storage requirement.
* SMT components provided must be sealed tightly or taped firmly. Sending them loose may cause components damage and the production delay.
