9. Four-layer and multi-layer connections
Standard four-layer, šestivrstvých to dvanáctivrstvých PCB:
material of the inner layer: The basic model for the creation of four-layer plates bearing pads used double-sided FR4 board thickness. 1.0 mm, clad with 18/18 micron or 35/35 microns.
Six-layer board is basically formed by laminating the prepreg thickness 200 micron two-sided boards strength 0.4 mm, clad with 18/18 micron or 35/35 microns. This core is laminated MATERIALS outer layers. Power lamination is about 200 micron on each side. The resulting plate thickness is 1.5 mm. Tolerance of the resultant force PCB is + / -0.1 mm.
Construction osmivrstvých boards based primarily on requirements for making blind or drowned prokovených holes. The basic design is based on three internal double-sided laminated boards with thickness of 0.2 mm layers of prepreg thickness of 0.2 mm and laminated copper foil thickness of 18 or 35 microns. On these films then there is a layer TOP BOTT board. The resulting power PCB is 1.50 mm.
Similar versions have ten and twelve-boards.
Another composition of the inner layers and the resulting thickness of the bearing pads may be required when ordering.
We also produce special panel of 26 layers for CERN.
- outer layers of material: copper foil 18 micron forces or forces 35μm.
- outer layer electroplating processes in the manufacturing process and finish hot dip tin can show amplification of PCB in conductive go up to 100 micron on each side of the prescribed strength bearing pads.
- Drilled according to drilling data as a via or blind, or sunk holes
- Solder mask made fotoprocesem
- electroplating tin
- Halovaná Cn100C solder - not recommended justification unnecessary thermal stress.
- galvanic nickel coating and electroplating gold
- Treated by OSP
Maximum size:
380 x 400mm electroplated tin
300 x 400mm Solder Mask HAL
300 x 400mm gold plating
300 x 400mm OSP
standard production bases:
data format GERBER with control prints. The sequence of layers of plates must be clearly defiováno nezáměnými description
positive film originals themes, solder masks and printing. I Delivery films require delivery of documents in a data form for the calculation of the production process.
drilling data format EXCELLON. Blind or sunk holes must be precisely defined by a separate drilling data with a clear entering between the layers to be made.
enter dimensions DPS, drawing or milling. Other designs and assignments are subject to negotiation in order DPS. |
