Since the enforcement of the RoHS Directive on July 1, 2006, there has been a growing trend in the shift to using lead-free solders for the surface mounting process to produce various electric and electronic devices.

Lead-free solders, requiring much higher temperatures when applied in the reﬂow furnaces, however, have created various serious problems such as poor soldering wettability, coplanarity, warpage or twisting of connectors, SMDs and other devices on the production lines.

CORES, to cope with these problems, taking advantages of its know-how and expertise relating to its own similar shape observation modules using thermal control, has developed core9050b, which provides similar environmental conditions to real reﬂow furnaces and permits easier inside observations from wide angles.

core9050b, thus, enables you to look to see the wettability of applied solders when they are melting at high temperatures as well as every shape change or deformity of target work pieces.

Real-time observations on solder wettability at high temperatures

core9050b adopts a most SDM-friendly convectional heating method and has allowed the realization of excellent thermal conductivity efﬁciency and the duplication of similar environmental conditions of reﬂow furnaces applying lead-free solders.

Omni-directional observations from wide angels of 360°horizontally and 180°vertically

core9050b, equipped with CORES’ epoch-making dome-shaped hemispherical glass, permits omni-directional visual observations of any shape change of electric and electronic devices and PWBs. Its spotlighting, capable of easy light amount and zoom lens adjustment, provides core9050b with fully sufﬁcient depth of ﬁeld and clear images for super minute observations of the target.
