What is Maxim's definition of lead-free (Pb-free)? Lead-free is defined as the non-intentional use of lead (Chemical symbol Pb) and less than 1000ppm in a homogeneous material. In an IC package, Pb is commonly found in the external lead finish or plating. Lead-free Hand-soldering – Ending the Nightmares Most issues during the transition seem to be with Hand-soldering As companies transition over to lead-free assembly a certain amount of hand-soldering will always be there. An article from Tech Search International last year did say that in Lead free alloys will eat away your tip a bit faster, and you will need to clean the tip more often (oxide forms much faster on the solder on the tip). At first I hesitated to switch, my first'experience was with a cheapa$$ soldering iron (directly to mains one) and cheap "Lead Free" solder. Lead free solder is a bit more expensive (I payed ...
Lead-Free Electronics Follow Weapons Systems and Platforms: For more than 50 years, the electronics industry has relied on tin-lead (SnPb) solder as the primary means of interconnection between electronic devices.

Except for the cases where forward and backward compatibility of lead-free (LF) components is critical, the answer is YES, you can mix. I remembered 2004 to 2006 when RoHS switching programs began to assure compliance with EU RoHS, it was common we did not have a clear idea about which components were and which one were not LF/RoHS. The main types of solder are lead and lead-free. You can use both for electronics, but it can be easier to work with lead-based solder.

In electronics, a lead (/ ˈ l iː d /) is an electrical connection consisting of a length of wire or a metal pad (surface-mount technology) that is designed to connect two locations electrically. Lead free solder composition is different from composition of leaded solder. There is NO Lead (Pb) is Lead Free solder.Lead Free Solder is taking rapid momentum around the world after the EU (European Union) Directives to wipe off lead (Poison) from electronic soldering considering its health and environmental effects.
Lead-free soldering. Therefore it is not possible to transfer these electronic systems to go Lead-free. Reliability issues As part of the development of Lead-free technology, reliabil-ity testing has been carried out. With the use of pure Tin, a well-known effect comes back into play: Tin whisker formation. At the moment, it is possible Section 1417 of the Safe Drinking Water Act (SDWA) establishes the definition for “lead free” as a weighted average of 0.25% lead calculated across the wetted surfaces of a pipe, pipe fitting, plumbing fitting, and fixture and 0.2% lead for solder and flux.
Electronics Definition – Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. Lead-in definition, something that leads in or introduces; introduction; opening. See more.
The more common lead-free solder systems have a higher melting point, e.g. a 30 °C typical difference for tin-silver-copper alloys, but wave soldering temperatures are approximately the same at ~255 °C; however at this temperature most typical lead free solders have longer wetting times than eutectic Pb/Sn 37:63 solder. Lead-free Electronics provides guidance on the design and use of lead-free electronics as well as technical and legislative perspectives. All the complex challenges confronting the elec-tronics ... Indeed, the draft Solders in Electronics report indicates that no metallic alternative to lead is free from environmental concerns. For instance, whereas lead may pose a greater public health problem than SAC solder, the latter uses noticeably more energy than lead–tin solder. But the presence of today’s substitutes is good enough for ...
