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 including Deca–BDE is 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 assembly subcontractors use lead-free solder paste compliant to RoHS.
|
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, AN0161, 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. Does Zilog’s RoHS compliance and “G” products involve changes to the integrated circuit (die) itself?
|
| No, compliance to RoHS requirements and Zilog “G” parts involves changes to the packaging of the integrated circuit such as the molding compound or lead finish. |
13. 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. PACKAGE | MSL (LEVEL) | LQFP | 3 | LBGA | 3 | QFP | 3 | QFN | 3 | PLCC | 3 | IRDA | 4 | SSOP | 1 | SOIC | 1 | PDIP | N/A |
|
14. 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.
|
15. Do the lead-free products meet UL94 V-0 Rating?
|
Yes, these products meet the UL94 V-0 Flammability Rating.
|
16. Is there a cost-added for lead-free products?
|
There is no cost adder passed onto our customers.
|
17. 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.
|
18. Are Zilog's assembly subcontractors prepared for lead-free processing?
|
Yes, Zilog has been working very closely with our subcontractors during this program.
|
19. 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 https://www.Zilog.com/quality/zan03-0013.pdf.
|
20. Will Zilog provide an Application Note on lead-free product use? |
Yes, Application Note AN0161 is available on our website..
|
21. 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) including Deca-BDE or 0.01% by weight in homogenous materials for cadmium. |
