wave soldering

Applying liquid solder to the underside of printed circuit boards in order to bond the chips and discrete components that are placed on top of the board and whose metal leads (pins) extend through the board. The board is moved across the solder, which adheres to the flux and bonds the pins to the board. Contrast with reflow.

Lead-free Wave Soldering, Some Insight on How to Develop a Process that Works, Available from: http://www.
When you have both surface mount (SMT) components and through-hole (TH) components you have to process the PCB through both a reflow solder process for the SMT components and a wave soldering process for the TH components.
Most wave soldering fluxes are designed to maintain activity and reliability across a wide process window, from fast and cool profiles to slow and hot ones.
We are convinced that Air Products' Inert Wave Soldering technology will bring quality improvement and cost savings by reducing defects and flux usage, as well as help protect the environment by minimizing solder dross, hence bringing competitive edge to its customers," says Simon Lian Sui Ren, editor-in-chief of SMT China magazine, in summarizing the comments from SMT China Vision Awards judges.
With the reduced process windows for lead-free soldering, especially wave soldering with thicker boards, companies may evaluate VOC containing no-clean fluxes.
It is important to follow the supplier's specifications for wave soldering surface mounted components.
This value leader brings innovation and unparalleled process flexibility to the three main sub-systems of a wave soldering machine; the fluxer, preheat and solder module.
THE IMPLEMENTATION a lead-free wave soldering process will be successful only when multiple challenges are addressed.
Due to the many wave solder-related issues identified with the 305/405 family, like copper dissolution, shrinkage tears, pot corrosion and material cost, alternative alloy options for wave soldering continue to proliferate, and at a relatively rapid rate.
In 1957, Electrovert introduced the concept of mass soldering to North America and followed that with development of the Lambda wave, which literally "shaped" the wave soldering process.
