Gerber data is absolutely essential for calculating a quotation. The printed circuit board manufacturer needs these for quoting. To ensure smooth production, intelligent CAD data should also be provided. All common file formats such as OBD++, ASCII files or IPC-2581 are supported.
The following information defines the requirements for electronic production at Ginzinger electronic systems and is needed for a quick and uncomplicated processing:
Assembly designation "TEST123
Assembly type SMT one-/two-sided; THT
PCB data:
PCB dimension (l x w [mm])
Copper layers and thickness Number/assembly
Base material and thickness FR4/xy mm
Color solder resist Standard is green
Assembly print Yes/No/Color
Surface Electroless Nickel-Gold; HAL
Contours fritted Yes/No
Impedance controlled LP Yes/No
IPC-A-610 Class 2 or 3
###IMAGE2###
Component manufacturer fixed bill of materials
Customized components
Functional test
AOI
Climate test
Further tests:
Test report Yes/No
UL marking of LP Yes/No
Customer specific label Yes/No
The manufacturing data and plans are ideally sent as a ZIP compressed file to the customer consultancy.

Parts list
The following information is required for the individual components:
Component reference number(s) - consistent with assembly plan
Description incl. tolerance or manufacturer and manufacturer designation
Type of construction
Number of pieces per assembly
NOTE: Preference is given to parts lists in XLS and CSV formats.
Further data
Circuit diagram as PDF
Test instruction
If available: Impedance calculation of the printed circuit board
Materials to be provided
NOTE: Providing materials should ideally be avoided, as sub-optimal component packaging can result in significant additional costs.
