| 1. When can I obtain lead-free product from ZiLOG? |
| ZiLOG-qualified lead-free products have been available since
September 29, 2003. |
| 2. How can I determine if the product is lead-free? |
| For Integrated Circuits: ZiLOG identifies lead-free product with a "G" (indicating
environmentally friendly Green package) in the ZiLOG product numbering system.
(e.g. Z86C0408SSG)
|
| For Stressed Parts: For parts that undergo special testing such as burn-in the "D" designator becomes "J" when in comes RoHS-compliant (e.g. Z84C9008VED1380 becomes Z84C9008VEJ1380)
|
| For IrDA: A special lot designator (SL) "2090" has been added to the original part number (e.g. ZHX1810MV115THTR becomes ZHX1810MV115TH2090TR.)
|
| For Die Products: No changes will be made to our die products naming. ZiLOG dice are already compliant even before the RoHS directive was enforced.
|
| For Modules/Tools/Kits: They can be identified by the presence of a "G" suffix after the original product number (e.g. eZ80F915050MOD becomes eZ80F915050MODG)
|
| 3. Is it really 100% lead-free?
|
| Yes, ZiLOG uses 100% Sn (Tin) for our lead-free products
|
| 4. Aside from being Lead-free, will the "G" products be able
to meet the RoHS Directive?
|
| Yes. The content level for the six RoHS substances is well within
the restriction limits set by the EU directive. |
| 5. What is the typical plating thickness for your leadfree
finish?
|
| Our limits are set at 300 - 800
m
inches, however typical values are at 400 - 600
m
inches (10.16 - 15.24
m
m) |
| 6. Do you employ an annealing process?
|
| Yes, our assembly subcontractors use a 1-hour post-plating bake @
150
°
C annealing step in their process
|
| 7. What about lead-free solder paste?
|
| ZiLOG subcons use Sn (Tin) based solder with approximately 4% Ag
(Silver) and .5% Cu (Copper)
|
| 8. Is there a change to the reflow temperature?
|
| Yes, lead-free "G" products are processed at a higher reflow
temperature requirement, please refer to our "Lead-Free Solder Reflow:
Packaging Application Note, AN016101-0703, for specifics.
|
| 9. What is the maximum temperature that the "G" products can
withstand? |
| Our "G" Products are rated to withstand up to 260 degrees Celsius
for 20 seconds. |
| 10. Can "G" parts be soldered using the Non-"G" parts solder
profile? In other words, if we started changing our production to Green only,
do you think that this would be a problem?
|
| "G" parts are compatible with a leaded reflow process. They are
backward compatible except on BGA packages. The lead free soldering process
typically uses a higher temperature. The non-"G" package may not be robust at
these higher temperatures. Therefore, we cannot use non-leadfree packages in a
higher temperature lead free soldering process.
|
| 11. Does the molding compound stay the same?
|
| No, lead-free products require the use of environmentally friendly
"Green Compound" to compliment the higher reflow temperatures. ZiLOG lead-free
products were qualified with "Green Compound".
|
| 12. Will the change in materials affect the moisture
sensitivity of the ZiLOG parts?
|
| No, respective moisture sensitivity levels will remain the same
for the corresponding packages.
|
| 13. Is the molding compound colored green?
|
| No, the "green" refers to the environmentally friendly nature of
the compound and not the specific color of the material |
| 14. Do the lead-free products meet UL94 V-0 Rating? |
| Yes, these products meet the UL94 V-0 Flammability Rating
|
| 15. Is there a cost-added for lead-free products?
|
| There is no cost adder passed onto our customers |
| 16. Is ZiLOG converting all products to lead-free?
|
| ZiLOG plans to convert to 100% RoHS compliant products as a
standard in the future. We will manage exceptions based on customer need and
requirements
|
| 17. Are ZiLOG's assembly subcontractors prepared for lead-free
processing?
|
| Yes, ZiLOG has been working very closely with our subcontractors
during this program.
|
| 18. Can I obtain ZiLOG's lead-free product qualification
report?
|
| Yes, this report can be requested through your local ZiLOG sales
support organization. This is also available at
http://www.zilog.com/quality/zan03-0013.pdf |
| 19. Will ZiLOG provide an Application Note on lead-free
product use?
|
| Yes, Application Note
AN0161 is available on our website. |
| 20. What does ZiLOG mean by "Product is non-RoHS compliant"?
|
Non-RoHS Compliant means that the item does not meet one or more of the restricted materials limitations as defined in EU Directive 2002/95/EC as repeated below:
Maximum concentration value, by weight, of 0.1% in homogenous materials for lead, mercury, hexavalent chromium, Polybrominated biphenyls (PBB) and Polybrominated Diphenyl ethers (PBDE) or 0.01% by weight in homogenous materials for cadmium.
