T-Tech milling : 0.25mm ( NOTE: Varies depending on material, we can go smaller but there is a risk of losing a pad / track ) S103 milling : 0.25mm (NOTE: we can go smaller but the cut my not be uniform)Ĭhemical Etch : 0.3mm (smaller can be done if professional masks are produced from an external supplier) T-Tech milling : 0.28mm (NOTE: we can go smaller but the cut my not be uniform) Minimum separation between tracks and pads T-Tech milling : 0.5mm to 2.5mm | S103 milling : 0.5 to 3mm | Chemical Etch : Any | Laser ablation : 0.2 to 7mm T-tech milling : 430mm x 300mm | S103 milling : 220mm x 300mm | Chemical Etch : 220mm x 300mm | Laser ablation : 220mm x 300mm PCB Specifications Minimum & Maximum Dimensions Material Size (Bed Size) The machines have different design constraints thus we can cater for most types of PCB (Analogue, Digital, Antennas, Wave guides, Micro Strips, mixed signal, etc) Below gives you the information required for us to manufacture your board.

We can produce Multi-layer, double or single sided boards on various substrates with optional through-hole plating, tin coating, solder mask and idents. The etching and CNC milling machines are in the EE workshop (T-Tech Quick Circuit 7000, LPKF - Protomat S103 and mega Roto - Spray). In the department there are 2 CNC milling machines, a spray etch tank and laser ablation system to produce PCBs. Holes, slots and edges are cut using ether a cnc milling machine or laser ablation PCBS are produced using various methods and technologies depending on the type of pcb the methods below are used to remove copper from copper clad boards
