This finish was requested by customers and recommended after onsite tests were completed on boards with OSP, immersion silver, Pb-free hot air leveling (HAL), and ENIG.
Extensive testing on both vertical and horizontal hot air leveling machines has allegedly shown the solder also provides smooth surfaces with uniform depositions on pads, traces and through holes when compared to tin/lead coatings.
Scapa has made available a high temperature masking tape for low static protection of delicate gold finger or rhodium PBC contacts, assembly holes and components during hot air leveling or wave soldering processes.
Instead of stenciling paste, a flux is deposited over the solder coat, using hot air leveling.
Says Lovell, "this used to be a hot air leveling world, and since BGA, things had to be flatter.
This study investigates whether satisfactory control of the lead-free hot air leveling process is possible.
Mark Racic and Sherry Goodell, "No-Lead and Horizontal Hot Air Leveling," Nepcon West Proceedings, February 1995.
In wave soldering and hot air leveling, molten solder experiences a rapid heat loss at the point where it contacts the board surfaces and component leads.
While these traits can be somewhat dealt with in wave soldering, they're almost insurmountable in hot air leveling.
com), a small, privately owned printed circuit board (PCB) fabricator, has finished pilot testing a lead-free hot air leveling (HAL) process that meets its customers' requirements with a minimum of disruption to its manufacturing processes.
