4.FAQ 

Q: Do I have to use an FR4 material with the highest Td (Td = decomposition temperature) for lead-free soldering? 

A greater Td value is preferable, especially if the board is technically complex and exposed to a number of remelting solderings, but this can lead to higher costs. Knowing your assembly process can help make the right choices. 

Q: Why choose your company while SZ has so many competitor? 

10 years gold supplier experience with experienced management team & hundreds of long term cooperation customer.

Q: How do we know your quality? Do you offer free sample? 

Yes we can offer sample, but you have to pay first, once you do mass production from us, the sample fee will pay back to your account! I believe we can do long term business! 

Q: Which PCB surface is best for lead-free soldering? 

There is no “best surface”; all surfaces have their pros and cons. Which one you should choose depends on many factors. Please consult our technicians.
