Custom Fixture Designer Demonstration Guide
Step by step guide of Web Fixture Designer for 6 pin 0.1" pitch Pulse Transformer
Step1 - Example - 6 pin 0.1Inch
This page will describe the steps needed to design a fixture for this simple 6 pin pulse transformer with a a 0.1 " x 0.4 " footprint, using the online Custom Fixture Designer.
A full test description of the part is here
Step 2 - Dimensional drawings and pin configurations
First refer to your datasheet, or manual measurements to find the separations of the pin contacts you need for your design.
In this case, we find
Row pitch = 0.4 inches
Pin pitch = 0.1 inches
Step 3 - Find the Greatest Common Divisor
The designer works by giving you a grid on which to place your chosen connectors.
First, we must find the Greatest Common Divisor (Highest Common Factor) for your dimensions, that is also one of our available grid sizes.
In some cases this may be obvious (eg 0.1" for all RM type transformers).
For more complicated cases, we have also provided an on-line tool for you to enter your dimensions, which will then advise the grid size to use.
For this example ;
We entered 0.1 inch and 0.4 inch.
The tool advises to use will use grid side of 0.1"
1 cells for the 0.1 inch dimension,
4 cells for the 0.4 inch dimension.
Step 4 - Grid Selection
Select the gid size we have found in the above.
Step 5 - Select Parts
Select a connector type from the drop down menu.
You can use several different types on one design, if you wish.
Click the button "Explore parts for more details" to see information on the available types.
Step 6 - Place Connectors onto Grid
Click on the grid to place the connector.
You can click placed connectors again to remove them..
The grey square areas show restricted areas where additional parts cannot be placed.
Here we have placed
a) 6 small kelvin blades (100-161B) with
4 cells separation (0.4") in the X direction and
1 cells separation (0.1") in the Y direction.
b) 4 x 3mm holes (100-164A) for mounting our own a toggle clamp later
c) 2x 10mm holes (100-164E)for adding our own test sockets later
d) a 10mm raised area (100-165A) as a locating guide.
When finished then click NEXT.
Step 7 - Select Wiring to AT Nodes
Next you need to connect your connectors to your chosen AT test nodes.
You can either
a, click and hold on the connector, and drag and drop these manually onto each node
b, use the Auto wiring button to instantly connect them to the nearest node
Finally enter your deign name and click finish.
Step 8 - Finished design and costing
A summary of your design. a unique design ID and and costings will now be shown for your design.
This can be recalled later at any time.
If you would like email confirmation of this costing as a formal quote, then please click "email me a formal quotation"
Step 9 - Build and print custom fixture
This design was them manufactured and is show to the right.
The 4 x 3mm holes were used to mount a toggle clamp as shown.
The 2 x 10m holes were used to add 2 x 4mm safety sockets for optional DC1000 connections for DC Bias testing if needed.
