文档介绍：IPC 1757 Process Chemical Standard
Connecting the Digital World to the work®
IPC 1757 Status
Committee pleted work on the proposed standard.
Intention is that this standard would be used to report the use of certain process chemicals where there is a regulatory requirement regarding the use of these chemicals. Examples are:
Ozone Depleting Substances
PFOS/PFOA
Certain Glycol Ethers
This standard is not intended for use to obtain confidential or proprietary information regarding suppliers’ processes.
Proposed standard includes a flowchart to aid users in determining whether to report under IPC-1752 or IPC-1757. If the use of a chemical is reportable under both standards, only the IPC-1752 standard should be used for reporting.

Decision Flowchart for Reporting Using IPC-1757
Note1: Threshold concentration limit in Product = A
If the product is not allowed to have detectable concentrations of the substance, then A = 0 or A = Analytical Detection Limit.
Note 2: Threshold concentration limit in Process = B
If the product is not allowed to contact the substance,
then B = 0 or B = Not Intentionally Used.

Example 1 - Plating solutions - Metal additive
Chemicals used in manufacturing e into physical contact and e a part of the finished product.
Process Description: An electroless plating formulation of a non-RoHS metal contains small amounts of a RoHS Metal of Concern (RM) that is used as a bath stabilizer. RM can co-deposit into the electr
