SOME IDEAS FROM KAUFFMAN ENGINEERING...
By using as much automation as possible you can build quality into your sub-assemblies. In your industry you cannot afford signal or power loss due to loose or ineffective connections. In some cases, automation can be more expensive in the lower initial volumes but can actually save money over time.
In many cases the industry standards will dictate certain wire types. Kauffman Engineering recommends that you look at the wire early in the design to insure it meets RoHS, REACH, or whatever other requirements you have. Too often engineering can find the perfect connector for an application only to find out the wire insulation or style prohibits its use.
We all want to help the environment. Amazingly, many subcontractors have no green policy whatsoever. If you want to tell your customers how much you care, make sure your suppliers do too.
