Hi   All ,

 What are some ways to DFM for high copper? Our customer has asked on 2-4 oz designs, HDI.
Without the designs to show, some have plated filled over vias, laser drilling, and blind and buried vias ( "viers"). The material is 175 Tg, so lead free is not coming for free as well.

Suggestions?

TIA
Larry Russell

I'm trying to understand what causes PCB to increase in prices.  We have narrowed down to few items.  

 

1. Buried via 

2. Blind via

3. 4oz copper compare to 3 oz copper

4. Laser drilling

5. Nelco material vs the Nanya Material

6. routing tolerance

7. hole size tolerance

8. thickness tolerance

 

Please let me know if  you  can tell us something about our designs that makes it more expensive and how we can change it to make it less expensive.
