Technical Sourcing Checklist

Information Needed for Accurate Quotation & DFM Review

To ensure a rapid turn-around with an optimized stack-up proposal, our engineering team evaluates the following technical parameters:

STEP 01

Mechanical Layout & 2D/3D Files

CAD drawings (DWG, DXF, STP, or vector PDF) specifying overall dimensions, cutouts, window locations, and tail orientation.

STEP 02

Graphic Artwork & Color System

Print-ready artwork with precise Pantone (PMS) or RAL color codes, selective texture placement, and transparent window requirements.

STEP 03

Circuitry & Tactile Selection

PET silver conductive ink, flexible FPC, or PCB backer; choice of stainless-steel metal domes, polydomes, or flat non-tactile switch actuation.

STEP 04

Interface & Environmental Needs

Connector pitch (e.g., 2.54mm, 1.0mm ZIF), specific 3M adhesive specifications, operating temperature range, and IP rating requirements.
