Our special quality can be measured in the following facts:
We use first-choice laminates approved and certified by UL, NEMA, DIN, IEC and others.
Several types of laminates such as FR2, FR3, CEM1, FR4 and PTFE are available in different thicknesses and copper clads. FR 4 e.g is available in thicknesses of 0.5, 0.8, 1.0, 1.6, 2.0 and 2.5 mm with either 18, 35 or 70 microns Copper. The max. panel size is 510 x 1150 mm. Our cutting service provides sheets down to 50 x 50 mm min. size, with an accuracy of 0.1 mm.
The boards are protected against mechanical damage and unwanted exposure by a special, blue coloured adhesive paper. Due to this protective paper, no flitters appear when cutting or milling the boards.
Each board is subjected to chemical and physical controls and tests before and after coating.
A shelf live of more than 1 year under normal storage conditions is guaranteed. Even 10 year old boards still work.
We can coat boards that you supply with photoresist. The max. board size is 530 x 1160 mm, the min. board thickness is 0.3 mm. Our pre-sensitizing service includes cleaning, double sided coating in dip technology, pre-aging, optical control and protection foil. Attention: dip rim 10mm on top and drip rim of 10 mm at the bottom will reduce usable size by 20 mm on the short side (530 mm will go down to 510 mm). The rim is on request removed without charge.
New ! Bungard Cotherm:
For many applications customers demand a better thermal dissipation (LED). One possible solution for heat problems are so called metal core boards, which consists of a 35 µm copper layer, a 100 µm isolation layer (FR4) and a 1000-2000 µm Aluminium layer.
Bungard company offers this PCB type with brand name Cotherm. Cotherm is available with or without photosensitive resist and in these formats:
Metal Core Boards Cotherm 1000/100/35 µm; Format 530 x 1180mm (1,0 mm; 1 x 35 CU);
Metal Core Boards Cotherm 1500/100/35 µm; Format 530 x 1180mm (1,5 mm; 1 x 35 CU);
Dripping and clamping rim reduces the format to 510×1150 mm for Cotherm with photocoat.

We cut down all boards to non-standard sizes on request. The maximum board size is 510 x 1150 mm, the minimum size is 50 x 50 mm. Rests will be included.
Boards >= 2 mm will be cut by saw. Saw cutting loss will be 3 mm per piece.
