| Computer-aided
manufacturing (CAM) streamlines the transfer of complex
designs from our customers to the PCB shop floor. |
| dsi has
implemented EngenixTM, a rules-based software that automates the front-end engineering of a job. Links
to the CAM data extract and analyze your gerber files in a matter of minutes. Pre-programmed scripts generate stack ups.
BOMs and travelers that can them be optimized with ERP integration. In other words, the front end just got faster!!
Up to 20 potential different stack ups may be generated and one selected based on best fit, best balance, best cost, inventory on-hand
or combination of variables.
|
| EngenixTM uses
integrated Polar Instruments' impedance calculator to calculate and verify impedance values. A library of unique
engineering specifications can be created and each job can be checked and flagged for violations. Web-based browsers allow critical engineering
data to be available across multiple users and on the shop floor.
|
| dsi
uses Genesis 2000, an integrated software package, which
can cut cycle times and increase yields through extensive design
for manufacturing (DFM) programs. Various output options
allow data to integrate easily with third-party programs such
as the Excellon drills, CNC routing machines, electrical test
systems, automated optical inspection (AOI) programs and more.
|
| A
single database file of your design stores and controls all
of the programs necessary to manufacture a circuit board.
Multiple CAM stations allow us to process jobs concurrently and output
directly to film plotters to create tools. An ODB++ format
allows these files to be viewed and shared between CAM, Product
Support Engineering and Sales. |
| dsi
has written automated design rule check (DRC) scripts to
optimize circuit design. These scripts check for dangling
traces, space violations, annular ring violations, shorts on
inner layers, adjacent holes, and potential slivers. Problem
areas can be printed using a screen capture option for further
review or sent to a customer's design engineer to resolve. Any
problems are then communicated to the customer. dsi's
policy is to wait for customer approval before making changes. |
| After
the design is reviewed by dsi's product support
engineers, automated design for manufacturing (DFM) scripts
manipulate the files for the PCB shop floor. The DFMs begin
with the step and repeat process to panelize the board, generate
registration coupons and military coupons, etc. The
outer layers are reviewed for layer-to-layer copper balance and Genesis will
automatically balance the design by inserting copper
robbers around the panel; but,outside the actual board areas. The
total square inches of copper is listed on the panel itself
to assist production during the pattern plating process. |
| An
initial net list or "golden" net list is generated
from the gerbers to identify all end points for electrical testing.
After changes are made during the engineering review process,
a modified net list will be generated and verified against the "golden"
net list to confirm design integrity. If a customer net list
is supplied, the modified, gerber generated net list is compared
to the customer net list to confirm accuracy. Discrepancies
at any checkpoint are investigated and the customer is contacted
as necessary. |
