ASSCON\u2019s Vapor-Phase Reflow Soldering machines set
\nthe benchmark in soldering technology.
\nThe modern design of the machines and the physical laws
\nof the process permit to defect-free soldering of the most
\ncomplicated SMT assemblies even with leadfree solder
\npastes. Components such as QFPs, BGAs, Flip-Chips as
\nwell hybrid assemblies may be processed with high quality
\nresults.
\nThe machine series VP 1000 is offered in two model variants
\nfor assemblies with maximum size of 610 x 460 mm
\nor 610 x 610 mm.
\nThe machines are particularly suited for users who process
\nproduct with frequently changing assemblies in small
\nand medium sized quantities. Universal workpiece carriers
\nmake the systems very flexible.
\nThe physical laws during vapor phase soldering guarantees
\ncompletely stable process conditions. The whole soldering
\nprocess takes place in an oxygen-free atmosphere.
\nOverheating of assemblies, damage to components and
\nde-lamination of printed circuit boards cannot occur, as the
\nmaximum solder product temperature cannot exceed the
\nboiling point of the medium.
\nThe heat transfer takes place during condensation of the
\nvapor on the assembly. By adjusting the energy supply during
\nthe pre-heating and soldering process the temperature
\ngradient is effectively programmable.
\nThis ensures a homogeneous energy distribution for the
\nwhole assembly. Therefore three-dimensional assemblies
\nmay be processed without any problem.<\/p>\n
Machine design
\nThe machine\u2019s construction is self-supporting. The machine
\nmodules include infeed and exit stations, soldering
\nzone, cooling and control.
\nThe key unit of the compact multi chambers machine is
\nthe process chamber made of stainless steel. Large area
\nheaters mounted on the outside are insulated external heat
\nradiation. Temperature sensors for heaters, fluid, vapor and
\ncooling zone temperatures ensure consistant process dependability.
\nThe efficient cooling zone of the machine is equipped with
\na special blower system, which circulates the medium and
\nflux residues, emanating from the assembly, through a
\ncooling cassette and on to an internal filtration cycle.
\nAn automatic filtration system for microfiltration of the heat
\ntransfer medium is integrated in the machine.
\nThe machine also features an integrated exhaust system
\nto remove vapors and odors that de-gas from the printed
\ncircuit boards outside of the process chamber. The controller
\nis pre-programmed for the connection of an external
\nblower.
\nThe process cooling system is integrated in the base of
\nthe machine.
\nThe machine\u2019s controller unit is located in an integrated
\ncontrol case and comprises switch, control, regulator and
\nsafety\/fuse elements for all function units. The process is
\ncontrolled and monitored with a failure message system
\nvia microcontroller with colour-touch-screen and intelligent
\noperational panel.<\/p>\n
Soldering process
\nUsing vapor as the heat transfer medium the solder product
\n\u2013 independent of its size or weight \u2013 is homogeneously
\nheated to pre-heat and soldering temperature. Geometric
\nparameters, such as component form, packing density, are
\nunimportant for the heating process. Due to the high density
\nof the vapor the oxygen is displaced from the heating
\nand soldering area. Consequently, no protective gases are
\nnecessary.<\/p>\n","protected":false},"excerpt":{"rendered":"
