It is important to follow the supplier's specifications for wave soldering
surface mounted components.
As a result, there is the need to determine whether wave soldering
can deliver defect-free processes at these higher lead densities, or if an alternative technology exists.
6,7) Fillet lifting is the separation on the topside fillet between the solder and the land at the end of wave soldering
During wave soldering
, the heat attacks the through-hole component via direct conduction through the wire leads.
will review some of iNEMI's Pb-free projects that focus on Pb-free processes in areas such as wave soldering
, rework and mixed soldering.
The selective aperture fixture effectively masks the areas previously soldered in the SMT reflow and non-selective wave soldering
process, while exposing only those areas to be selectively soldered.
To illustrate the concept, a Taguchi experiment was used to develop a robust process for Pb-free wave soldering
125" thick and eliminate hand soldering, wave soldering
, selective soldering, intrusive reflow and press fitting.
specializing in leaded and lead free PCB assemblies in small- to medium-size lots, today announced the availability of lead free wave soldering
for complex through hole assemblies.
iNEMI Lead Free Wave Soldering
Project; An Investigation of Reliability of Through-Hole Electrical Interconnects"
However, the company took equipment and floor space optimization one step further by teaming with a wave soldering
equipment manufacturer in adapting a comprehensive wave soldering
system capable of both lead and Pb-free wave soldering
A primary advantage is the elimination of the wave soldering
process and its associated tooling cost and potential handling damage.
