SOLDER COAT CO.,LTD.
Lead-free solder alloy at High strength, No Silver, low cost
/ Tough alloy CP solder LLS228N
Tensile Strength improves by addition of Sb compared with the conventional Sn-Cu Alloy composition alloy.
The shearing strength by the Thermal cycle test after mount device improves more than SAC305.
Flux spitting of flux cored solder decreases substantially.
