To all,
In an effort to reduce cost, our boards manufacturers are proposing to
remove the requirements for etchback. This is reported to be a saving of
10-15% of the bare board. For an equipment subject to be used in an
environment which may be similar to a car and possibly marine types,
questions are:
1- Do we put ourselves in a position where reliability will drop
significantly if etchback is not specified?
2- Is etchback normally used in the automotive industry for multi-layer
board if used? If not what alternative to use?
3- Is the 10-15% cost reduction realistic?
4- General consumables like computers, are they using this process?
Any other comments would be appreciated.
