Parts?
A7: Determined on a case by case basis.
Q8: What is the LIS policy on Lead-Free implementation?
A8: LIS will continue to supply requirements for both Lead-Free Parts and Non-
Lead Free parts per customer request.
Q9: What is the LIS policy on RoHS Compliant Part implementation?
A9: LIS has begun converting to ROHS Compliant mold compound on all plastic
Packages effective 1/1/05. All parts with date codes prior 1/1/05 are not made of
RoHS compliant mold compound.
Ordering Information:
1. RoHS Compliant (Lead-Free and PBDE-Free) Parts:
The part description must include the term "RoHS Compliant". Do not
include the letter "F", it must state RoHS Compliant. Purchase Orders that
do not specificately state RoHS Compliant will be shipped either "Leaded-
Parts"or "RoHS Compliant parts" depending on our inventory.
2. Leaded (Devices that contain lead) Parts:
The part description must include the term "Leaded Part". Purchase Orders
that do not specifically state "Leaded Part" will be shipped either "Leaded-
Parts" or "RoHS Compliant parts" depending on our inventory.
3. Disclaimer:
LIS will not be responsible for accepting the return of any parts that were not
ordered correctly by the customer.
