T5000 Series 5 Supercool

The Cirgraphics Model 5000 is a double sided, double drawer exposure unit suitable for high speed production of high resolution printed circuit boards, inner layers and photo imageable resists.
The unit is robustly built to withstand continuous working in good production environments. It has two powerful UV light sources with lamp output of 365Nm which is closely matched to the spectral responses of all of the current range of resists and the reflector system is designed so as to give a very even coverage of the drawer area and comparable exposure times with equipment having higher power lamps.
Any one of 4 power levels can be selected and stored in each of the 8 memories, so that all resists, from the very fast dry films to the much slower photoimageables, can be accommodated. The lamps are automatically switched down to 1kW whilst the shutters are closed, thus saving energy.
The main feature of this unit is Cirgraphics unique compartmentalised cooling system, which allows the vacuum area to be kept cool whilst the lamps are maintained at their much higher optimum working temperature. The vacuum drawer area is cooled by air which is forced over both sides of the drawer from the rear of the unit. When SuperCool is connected this air is refrigerated.
An external extraction fan is supplied with a length of hose to enable all the hot exhaust air from the lamp houses to be removed from the machine and ducted, if required, out of the production area. The optional SuperCool refrigeration unit will also require two 14" ducts, which are additional and subject to installation.
The double drawer system has a very fast motor drive with safety interlock buttons so that both have to be pressed simultaneously before the drawer will interchange. An additional interlock allows the drawers to be driven only when the drawer is closed correctly, avoiding unit damage. There is also a safety circuit to ensure that the drawers will not operate whilst an exposure is still in progress.
Exposure is controlled through a microprocessor based integration system that measures light within the UV spectral range and balances out the difference between sides of the board and the top and bottom drawer position. Eight memory channels are available allowing different exposure programmes to be stored.
The same microprocessor monitors all the functions of the machine and the exposure status, whilst the drawer positions are indicated on the mimic display situated at eye level above the main control panel. The programmes can be protected by a personal identity number so that their contents can only be modified by authorised personnel.

Optional Accessories
Glass to Glass Vacuum frame
A low vacuum glass to glass system can be fitted to replace the standard embossed polyester to glass assembly.
This unique system allows pcb panels of varying thicknesses to be processed at a high through-put and with accurate alignment of photo tools.
Various registration systems are available, with or without vacuum photo tool retention, for either the standard frame or the glass to glass frame and can be engineered to suit most customers requirements.
