Define High melting point solder

XRF Testing....an absolute necessity??

we shouldnt be talking about lead free we should be talking in terms of RoHS compliant. HMP solder is exempt in the directive even though it has a hig lead content (93.5%) as no other alloy will melt at the same temperatures 298. as HMP is exempt wi

Hi, The solder we use is Sn5Pb93.5Ag1.5. with a melting point of about 30 degrees.

High Temp Solders and their use

For high temperature electronics, operating in 225�C ambient environments, most solders can not be used. The high-lead solders all have difficulties of one sort or another. Is their anything new regarding useful high melting point solders? Especially

Hi, We are currently having issues with hand soldering High melting point solder wire. Can anyone give a few tips. We are Preheating boards to 120 deg C and using soldering irons @ 410 deg C. The quality is ok but the ts taking 20-30 seconds to c

What solder are you talking about and what reflow method are you using? High Melt Alloys: SN96 (Sn96/Ag4 or Sn96.5/Ag3.5) - Simliar to SAC305 although normally uses Rosin based flux that can required more extensive cleaning. Pb85 (Pb85/Sb10/Sn5) -

High Melting Point Solder with alloy composition of 93.5 Pb 5 Sn 1.5 Ag

With a melting point of roughly 300°C, you would need to have the product see temperatures peaking around 325°C at a minimum. (I would make sure the components and PCB materials can withstand these temperatures) Most convection ovens do not go over 3

HMP Lead free solder?

Electronics Forum | Wed Aug 31 06:33:04 EDT 2005 | Slaine

if a solder has over 85% lead its classed as RoHS complient because its difficult to achive the same melting point with anything else (298degrees). a few other alloys with a similar range are ; % % 266E266 82.6 Cd 17.4 Zn 271MP 100 Bi 280E2

You are asking a very good question which has been an issue in the industry for a long long time. For operating at 225C, you will need a solder with melting point no lower than 270 or even 280C. HMP solder is very difficult to come by. At this stage,
