Delamination effect in FR1 type PCB (Lead free soldering)

Electronics Forum | Mon Dec 30 08:14:45 EST 2013 | jax

I was unaware of any Pb-Free process capable FR-1 laminate... not to mention capable of Though Hole plating that would be expected when wave soldering. What is the Td and Z-expansion for the laminate you are using?

Hi, FR1 laminiate used is only for single side type and THD plating is not used. I have also attached laminate manufaturer's datasheet. Thanks,

It is a PCB material that has a woven glass / epoxy internal core and glass veil surface. It is in between the paper materials (FR1,FR2 and CEM1) and FR-4 as far as strength and cost. It is available in HiCTI material for high power applications.

Have anyone perform wave soldering on FR-2 and FR-1 printed circuit board with lead free soldering? Can you share the parameters(wave temperature,preheat temperature, contact time, wave height,etc,) used and did you do any changes to the wave solderi

Our R&D people are looking at the possibility of "Silver Through Hole" as an alternative to "Plated Through Hole" for our future PCB specification. Do any of you have any experience of this, advantages/disadvantages, etc. I'm told that the main reaso

Hi, We are using mixed technology in our PCBA. Would like to know whether there is any criteria governing/guiding the use of mixed technology in such aspects as: 1. Some SMDs cannot be used in some kind of PCB materials such as FR1? 2. Some SMDs are
