QUALITY AND ECONOMICAL ASPECTS OF SELECTIVE WAVE SOLDERINGAuthor: Zsolt Nemes
Date Published: 9/22/2002 Conference: SMTA International
This presentation highlights the principles of selective wave soldering, the different alternatives used for fluxing, preheating, soldering and board handling. Also, different programming possibilities and their expenditure will be discussed. It will be demonstrated that quality aspects such as hole filling, flux residue, thermal stress on components as well as failure rates are clearly in favour of the automated wave soldering method. A capital investment to change from manual soldering to automated soldering must also be studied from an economical point of view. It will be shown quantitatively under which circumstances a selective wave soldering machine becomes economically favourable.
Key words: selective soldering, pin in paste, solder joints, mini wave.
