Data Requirements:
The following lists the desired information that Ascentec Engineering
will use to design your fixtures and tooling. The desired data differs
depending on the product being designed. Please reference the Data Formats
section to determine the best format for sending
your data.
| Wave Solder / Selective Solder Pallet |
| Desired Information |
Purpose / Comment |
| Bottom-side silkscreen |
Usually a good source of component outlines. |
| Bottom-side mask |
Indicates which metal areas are masked and which are exposed |
| Bottom-side paste |
Used to determine which parts are added during the SMT process. |
| Top-side silkscreen |
Allows for correct position of holddowns, and indicates parts that overhang the image edge. |
| Top-side paste |
(optional) |
| Top-side mask |
(optional) |
| Fabrication Drawing |
The dimensioned fabrication or panel drawing if panelized during wave. Also contains valuable information including: PCB dimensions and thickness, layer stack-up, and board chemistry (substrate, plating, and mask types). |
| Additional Information |
Components that overhang the pcb edge: comp height, depth below pcb and overhang distance. Mounting hardware size/location. Height of components requiring connector hold downs. |
| Surface Mount |
| Desired Information |
