A NEW Bench Top Screen Printing Unit which is ideal for circuit
board and non circuit board applications. For circuit boards it can be used
to screen print component idents and solder masks with either conventional
silk screen stencils or photo-imagable inks. The height adjustment and registration
aids also make it ideal for conventional screen printing on a whole host
of materials including front panels and nameplates etc.
The Screen Printer allows different screen sizes from 230mm wide to a maximum external frame size of 508mm x 660mm (20" x 26") to be accommodated. Frames are held by a unique clamp which can be adjusted for frame thicknesses from 46mm to 20mm.
This new screen printer has many unique design features. For instance
the fitted Silk Screen Frame pivots in a polymer hinge block which eliminates
all unwanted "play" to allow accurate stable screen printing. Stability
during printing is further enhanced by height adjustable carriage having
a four point single element clamp device mounted on two rigid columns. This
height carriage allows the screen to be raised to allow the printing of
materials to 75mm thick.
The actual printing bed or Base Board sits on a fine adjustment mechanism to aid registration which allows a 0 - 15mm movement in both the X and Y directions. This stable 19mm solvent resistant Base Board can be removed for easy cleaning or replaced using the four threaded fittings with a customers own base board or printing jig.
For long term durability the complete unit is manufactured in a fabricated welded heavy steel construction with a durable powder coat finish.
Approx dimensions: 670mm x 655mm x 70mm
Approx weight: 23kg
Vacuum screen printing units ideal for screen printing component ident and solder masks onto printed circuit boards, as well as printing front panels, nameplates etc. The two sizes are available to handle, nominally, A2 and A1 paper sizes on the vacuum area. The maximum outside frame dimensions which can be mounted are larger than the vacuum area to allow for the frame thickness and surplus mesh surrounding the working area. The working surfaces are solvent resistant. Different screen sizes can be accommo-dated by the sliding screen mounting channels. Vacuum is provided by a Whisper Vacuum unit which is permanently mounted on the lower shelf on all machines supplied with a floor stand. A sliding plate isolates the vacuum from the bed when the frame is raised to aid substrate removal.
The screen frame is of substantial box section construction, epoxy powder coated and fitted with bronze brushed, hardened pivots. To accommodate differing thickness' substrates and adjust 'snap' the screen frame pivots and front stops provide a full 50mm (2") of vertical adjustment. An adjustable height stop limits lift and a counter balance weight can be adjusted to achieve precise balance for the majority of frame types. Both the A1 and A2 units are supplied fully assembled fitted to a stand with the Whisper Vacuum unit permanently fixed to the lower shelf.

Aluminium Silk Screens
Mega can offer high quality aluminium silk screens to fit a whole host of machines. Each frame has the silk screen mesh applied. Mesh is measured as threads per centimetre, 77 being suitable for the printing of solder masks and 120 for idents and front panel work. Some popular sizes are listed below. All dimensions below are for the outside of the frame. The frames are 38mm wide, the printable area is normally 25mm in on the mesh, ie. 63mm from the outside frame dimension. Alternative size screens and mesh sizes are available upon request.
