Excuse me, what do you mean temperature is too low? Do you mean the hand soldering temperature? Does this can solve the problem of pads lift? 
Hi,Liu,if your customer have to use hand soldering rework, I advice you use LFmaterial of Tg150 or Tg170.

主旨: [TGAsia] leadfree hand soldering temperature




Dear Sir, 
  
I have a customer who often complains boards supplied by us have pads lift issue when they do hand soldering rework. This customer is using hand soldering with temperature set at 320-349 degC for leadfree soldering rework and the boards supplied by us are with Tg130-140 degC only. We hope to have your expertise advice what is the common leadfree hand soldering temperature and if need to withstand 320-349degC hand soldering temperature, what Tg material should be used. 
  
Hope to receive your favourable advise. 
  
Thanks & Best Regards
