Good Morning Peter,
Depending on your budget constraints, there are several companies that have
machines with light shutters to point out the insertion location and a
carousel that opens the corresponding bin with the component to be inserted.
These systems can also perform lead cut and clinch after the component is
inserted into the board.  To name a few:  Blakell Europlacer, Royonics &
Contact Systems are the ones that I am familiar with and have used in the
past.
I would suggest doing some research on Poka Yoke, which means "mistake
proofing".  Some suggestions that I have used in the past would be the use
of mylar templates, work samples, color photographs, and color coded
drawings.  In parallel the component bins and tubes would be setup in
insertion order and color coded or numbered for visual management.
The other topic is to balance the line with respect to insertion time,
number of insertions and number of assemblers.  This is important when
establishing a "pull system" rathen than a "push system" using a standard
"slide line".
If you should need more detailed information, please do not hesitate to
contact me offline.

Subject: [TN] Throughhole insertion

Can anyone provide some guidelines/ rule of thumb on planning out a
manual throughhole insertion line? For example, how would one go about
assigning components to individual insertion stations to minimize human
mistakes?
