Upload Design

To receive a quote, click the “ Upload Design” link. Answer all the questions to ensure we can quickly and accurately respond. Once you submit your RFQ, a team member will gather information on availability, lead time, and costing. Manufacturing will audit “design for manufacturability” and component crosses, if necessary. Average quote time is 1 business day depending on complexity, component availability, and/or missing information.

Missing, incomplete, and inaccurate data is the #1 reason for delayed quotes.

Files & Information Required

  • Gerber (PCB Fabrication)
  • ODB++ (Pick & Place Equipment)
  • FAB Drawing (PCB Fabrication)
  • BOM in Excel or CSV (Component Sourcing)
  • Properly fill out the “ Upload Design” page

Revision

Rapid Prototypes require BOM & PCB revision. We deal with thousands of part numbers daily. If you require a change, be sure to REV your documents.

  • BOM required
  • Gerber required
  • FAB drawing required

FID

Fiducials are required on the PCB sides containing any SMT components.

  • Typical Fids sizes are between 0.5 to 1.5 mm round with a 3 x diameter solder mask keep out area.
  • Ideally the Fids should be placed diagonally as far apart as possible on the PCB.
  • Fids must be assigned as a component and prefer reference designator such as F1 or FID1.

Stencil

  • Mectronx recommends setting paste layer to 1:1. Our team will then work with our stencil providers to provide the optimal aperture opening, thickness, and coating.
  • If the customer modifies the paste layer, we will assume this is intentional and follow your design.
  • Mectronx rapid prototypes use production stencils. The stencil is customer property and available upon request. Stencils are kept on site for 1 year and then recycled.

Programming & Functional Testing

  • Functional testing & programming is required for production and on-demand manufacturing.
  • Optional functional testing & programming for prototypes.
  • All testing and programming must be clearly defined and provided by the customer.

Payment

  • Typical new customer payment terms are 50% due at receipt of PO; prior to part procurement. Balance invoiced upon shipment of product, Net30.
  • Tariff charges will be passed on directly to the customer at 1:1 rate.
  • Option to pay with Credit Card (customer to cover credit card surcharges)

Labeling

Rapid prototype labeling comes standard with date code and serial number. Custom options available upon request. Examples:

  • Barcoding
  • MAC address
  • Logos and product icons
  • Customer serial numbers

Shipping

FOB Oconomowoc, WI (Mectronx loading dock)

  • Standard UPS
  • Optional FedEx
  • SpeeDee Delivery Freight
  • Optional UPS Freight

Panel Design

Mectronx will panelize the PCB. If you have critical areas or keep-outs due to sensitive components please designate on the FAB drawing. De-paneling options include V-score, mouse bites, and pre-routed at the FAB house.

Standard Rigid

Listed below are our economical fabrication standards to help improve manufacturability and overall production time. See Advanced Rigid for complex designs not covered below.

  • Standard turn – 5 days
  • Quick turn – 2 days
  • Thickness – 0.031" / 0.062" / 0.093"
  • Solder mask colors – green / red / blue / clear / black / white
  • Silkscreen color – white / yellow / black
  • Copper weight – 0.5 / 1 / 2 / 3 / 4 oz
  • Standard finish – ENIG
  • Material – Stock FR4 Ventec VT-42 / VT-47 180TG
  • Min line & spacing for 0.5 oz copper – 5/5 trace/space
  • Min line & spacing for 1 oz copper – 6/6 trace/space
  • Min line & spacing for 2 oz copper – 8/8 trace/space
  • Min finished hole size for 0.031" & 0.062" thick board – 0.008"

Advanced Rigid

Advanced fabrication standards greatly expand design options for complex circuitry. Fabrication lead time and cost will increase on average 50% over standard rigid.

  • Standard turn – 10 days
  • Quick turn – 5 days
  • Thickness – 0.005" to 0.250"
  • Standard finish – ENIG
  • Material – FR4 Laminate / FR4 Getek Laminate / Rodgers 4003 / 4350 / Nelco N4000-13

Rigid-FLEX & Metal Core

Contact Mectronx at Email Mectronx

Stack-up Request

When requesting impedance controlled stack provide:

  • Target impedance
  • Trace width
  • Trace height
  • Layers on which the impedance traces are present
  • Spacing between copper components on controlled traces for coplanar or differential calculations

Rapid Prototype Inspection

All assemblies are inspected to IPC-A-610 Class II standard by 3 different trained inspectors.

  • Pre-reflow
  • Post surface mount
  • Post through hole assembly

Manufacturing defects are reworked following IPC-7711/7721 guidelines.

House Solder

Lead-Free (RoHS) No-Clean flux is standard.

Packages

  • SMT packages 0201 or larger
  • Fine pitch 0.4mm or larger

Mechanical Assembly

  • Calibrated torque drivers from 0.5 to 30 in/lbs
  • Hot Melt robot application
  • RTV robot application (slumping and non-slumping)
  • Air ionizers for LCD assembly
  • Laminar flow hoods for LCD assembly

Conformal Coating

Hand applied acrylic conformal coatings. Our house material is acrylic Humiseal 1B31. We can apply your specific material if the TDS states brushing is acceptable. In general, this would include most urethanes and acrylics, not silicone.

Encapsulation

Available for rapid prototyping and production. We have industry proven house materials, or we can apply your specific material. Mectronx works with Epic, Ellsworth, and Krayden to source and ensure we have the expertise to encapsulate your design properly.
