The technique

Material

Industry standard quality
  • FR4
  • 0.062in (all products)
  • 0.039in (1 & 2 layer only)
  • 1 ounce CU
  • Chemical Tin or HAL (both PB free)

Layout requirements

Any format and any outline are possible, without any extra charge!
  • Pad/Via Restring > 0.4mm/16 mil
    Via/Drill Restring > 0.3mm/12 mil
    (pad size minus drill diameter), at least tracksize/gapsize
  • Soldermask > 0.15mm/6 mil (size on solder-layer minus pad size on cs/ss)
  • Multilayer Antipads > 1.0mm/40 mil (pad size on negative innerlayer minus drill)
  • Minimum holesize: Drill-end diameter = 0.3mm (12mil)

Track/Gap

Singlesided pcbs:
  • minimum track size = 0.15mm (6mil)
  • minimum gap size = 0.15mm (6mil)

Doublesided / 4 & 6 layer pcbs:

  • minimum track size = 0.15mm (6mil)
  • minimum gap size = 0.15mm (6mil)

Area

The minimum area which you can order in PCB-POOL = 16 sq.inches.

PCBs with a smaller area will be charged at this rate. Where smaller PCBs are required, you can make your own panel to achieve the minimum area 16 sq.inches. This mini panel can only have one outline. We can step up your mini panel and route single pieces for only USD 10.00 flat rate rout.

We can set the panel for you - for free!

All prices include photoplotting (not delivered with boards) and all tooling costs!

Soldermask

Solder resist is a green covering in which clearances are made for solder areas (e.g. pads) and for SMD connectors.

These are therefore kept free from tinning in the soldering process. Applying soldermask means that tinning is applied more economically (so that flooding does not occur) and notably, the risk of shorting in finely structured boards is kept to a minimum. Also, soldermask results in greater air gaps between tracks. Last but not least, solder resist gives your board a more professional looking finish.

We use only photosensitive solder resist, applied either in liquid form or as a foil through a vacuum laminating process.

Soldermask flat rate (independent of size) charge USD 14.50 per side for singlesided and doublesided pcbs. If the soldermask on top and bottom layers are the same (i.e. no SMD's) USD 14.50 will only be charged once.

For 4-layer & 6-layer pcbs the soldermask is included in price.

Position print

Position print is white and can be printed on either or both sides (TOP and BOTTOM).

So as not to cover any pads, the position print in PCB-POOL® is clipped away from corresponding soldermask pads by 0.1mm(4mil). If you wish to order silkscreen, please note, that a correct adhesion in accordance with IPC standard is only guaranteed, if you choose the soldermask option.


Flat rate charge for position print USD 14.50 for singelsided, doublesided and 4-layer multilayer pcbs (independent of size).

Attention: Unless otherwise stated layers where an eagle file is in question layers 21 and 25 will be used to generate the position print.

E-Test

With electrical testing, all tracks are checked for breaks and shorting. Until now, e-testing of PCBs using a needle adapter or a flying probe was exorbitantly priced. Thanks to PCB POOL® these costs have been dramatically reduced!
