Fotoboard (2) Pre-sensitised 'FR4' Copper Board
The first choice for the production of quality printed circuit
boards. Fotoboard is a positive working, Photoresist coated, glass fibre printed
circuit laminate to BS4584 and MILSPEC MIL-P-13949GE GRN. The resist is applied
5 microns thick using a specially developed roller coating process which ensures
a particularly even layer. The resist is high temperature cured which, combined
with its tough plastic film laminate covering, results in a durable board which
can be handled, guillotined and processed with a high degree of safety. Inspection
at the development stage is simplified by use of a green dye in the Photoresist.
Fotoboard is 1/16" thick, 1 oz copper. It has a minimum shelf life of one year
and is available as both single and double sided. 2 oz and other thickness'
are available on request.

Flexible Polyester Laminate
A flexible laminate made from a 50µ polyester base with a 35µ copper coating and our photosensitive resist on one side. This laminate is ideal for prototyping. It is supplied in a light proof sealed bag and is not covered in a protective film.
Uncoated PCB Laminates
A selection of the same high quality FR4 laminate used for our other laminates without a Photoresist coating. It is ideal for use with dip coating machines, dry film laminators, screen printed resists and direct imaging via etch resist transfer or ink pen. All sizes are supplied as single sheets.

Drill Entry / Exit Board
MDF drill exit board for precision drilling with a CNC drilling machine.
FPC 16 (2) Pre-sensitised Economy Board
A fibre glass and paper composite laminate
manufactured to the same high quality standards as Fotoboard but giving
certain price and weight advantages. FPC-16 consists of two fibre glass
outer layers with a paper composite in between. The 1 oz copper thickness
and high quality Photoresist are the same as Fotoboard. The construction
of FPC-16 makes it light, easy to cut and drill. It also costs less to
manufacture making it cheaper than Fotoboard. Various single and double
sided options are available all supplied as single sheets.

Microtrak Resist Coated Laminates
 Microtrak laminates were previously supplied
by Instagraphic Products Ltd. The FR4 epoxy glass laminate is dip coated
with a high resolution positive working Photoresist. The Photoresist contains
a dye which gives a good contrast against the copper, allowing boards to
be easily inspected at the developing stage. Panels are protected by a specially
designed light-proof blue film which allows panels to be guillotined without
the risk of fracturing the Photoresist. |
