["Kai Keskinen" <kalevi@xxxxxxxxxx>]

You more need to worry about what PCB substrate material you are using. ROHS
compliant solders use higher temperatures that some PCB materials cannot
tolerate for multiple reflow cycles. Many of the PCB fabricators have been
doing experiments with various substrate materials so you should talk to
whoever is building your bare PBCs and who is populating your boards.

Subject: [SI-LIST] ROHS Compliance


Hi,
   We are converting one of the old PCB to RoHS compliance standards.
I am not very much sure about the process in Rohs.

We have changed all the components footprints as new Rohs  mechanical
packages & I added a note in Fabrication  drawing that the board has to meet
the Rohs compliance standards as RoHS plays more only in PCB fabrication.

  My doubt is whether I need to take any special consideration for the
routing & DFM issues.

Our board is 5/5 trace & spacing. Will this affect any RoHS standards.

Please let me know whether I need to take any care to meet the standards in
PCB CAD designing.


Thanks in Advance.

Regards,
Boopathy J
