Alchemy, designed and manufactured
by Cemco, has proven to be the preferred solder coater by many of
the world’s leading PCB fabricators and assemblers. Alchemy systems are
able to provide improved surface planarity, excellent solder
distribution, a clean bright finish and fewer defects.
The 'D type' has been designed specifically with low to medium capacity
facilities in mind. However, it is an ideal option for existing Alchemy
or other Leveler users where additional capacity for high quality
product is required, and where floor space is limited.
The system incorporates a panel align/rotator, allowing the system to be
installed in either straight line or ‘U’ configuration.
Alchemy's patented design uses computer controlled automation, providing
precision adjustments via a touch screen. Pre-set process limits are
continuously monitored and regulated. Leveling speeds up to 30 meters
per minute result in reduced solder contact time and a thinner
While the Alchemy 'D-type' is a low cost system it is still easily
capable of processing in excess of 1,400 panels per shift, with first
pass yields typically in excess of 97%. A combination of convection hot
air preheating and less active chemistry help to reduce thermal shock
and minimise absorption of surface organics. When compared with
alternative coatings, an Alchemy system is a cost competitive process.
