Customer Supplied Files & Materials Guidelines

Our Customer Supplied Files & Materials Guidelines are modeled after the internationally recognized IPC Standards. These standards help minimize cost, delays, and risk from unusual PCB designs and assemblies. For exceptional assemblies that fall beyond the scope of these parameters, Pro-Active Engineering will work with our suppliers to meet our customer’s needs. Below is a checklist that will help you prepare your files for manufacturability, ensuring the fastest, best quote we offer.

Customer Supplied Guidelines

Our Equipment

The following information is recommended for all component procurement, verification, inspection, programming the pick and place equipment, and assembly work instruction creation. An increase in cost or lead time may apply if the customer does not follow the recommendations listed in these guidelines.

Material Guidelines

The customer is responsible for providing RoHS compliant Bill of Materials if the assembly requires it. If required, Pro-Active Engineering will build assemblies in accordance with RoHS compliant processes. It is recommended that the customer sends extra parts due to leaders and/or attrition during the PCB assembly process.

Pro-Active does not experience much loss, but to be safe, Pro-Active would appreciate having a few overages to avoid any delays in assembly. Lead time may be impacted if the proper leader and/or attrition is not supplied. If you have expensive components or a minimum quantity of any component on hand, please contact your sales representative for details.

Parts that are properly shipped in anti-static carriers or moisture sensitive packaging will be treated with care while being inventoried, placed, and resealed. Any unused customer supplied parts are returned with your assembly.

Component Packaging Requirements
  • Each component shall be individually packaged, labeled with the BOM line item number, customer part number and/or manufacturers’ part number.
  • The following are acceptable packages of consignment/customer supplied components:
    • SMT reels
    • Cut tape
    • Thru-hole bulk or tape
    • Tubes / trays
    • Digi-key reels
  • SMT components not supplied on reels are required to be on one continuous strip of tape.
Bare PCB’s
  • We recommend having a silkscreen on your PCB that indicates polarity and 1st-pin markings.
  • All bare PCB’s require a 1⁄4 inch rail on all sides to accommodate machine handling.
  • A minimum of two fiducials are required for accurate component alignment and placement.
  • Minimum array size is 3” x 3”
  • Maximum array size is 17” x 17”
Overage Guidelines
  • Passive Devices (Resistors, Capacitors, and Diodes)
    • 0603 and larger footprints: add 10% and/or 20 pieces to build quantity. One continuous tape strip is required (splicing of tape is not permitted).
    • 0402 and 0201 footprints: add 50% and/or 50 pieces to build quantity. One continuous tape strip is required (splicing of tape is not permitted).
    • All others, add 20% overage.
  • IC's:
    • Under $1.00 - add 5% overage, or one piece, whichever is greater
    • $1.00 - $5.00 - add one piece
    • Over $5.00 - no extra is required
    • If IC’s are in tape media, one continuous piece of tape is required (splicing of tape is not permitted)
  • Thru-Hole
    • A minimum of one thru-hole or one percent, whichever is greater
    • Large volume jobs add 2-3% overage on inexpensive items (50 cents and less)
