Requested method of shipment?
Our intent is to always ship via the carrier you choose (in written) and to use your shipping account number if provided; however, all the carriers (UPS, FedEX, and DHL) have different pickup schedules during the day and evening. If your order is ready for pickup after the final pickup time by your requested carrier we will change the carrier, as we assume that it is more important to you that you receive your order on time as expected rather than what carrier is used. In doing so, we will not be able to use your shipping account number. We will ship it on our account and add the shipping charges to your invoice. If you request a change to this policy, we will be glad to hold your order until the following day's scheduled pickup by your preferred carrier.
Late deliveries
We work very hard to make sure all your PCB orders get shipped on time. There are occasions, however, when the freight carriers UPS, FedEX, or DHL have delays and/or make shipment errors. We regret when this happens but we cannot be responsible for delays by these carriers.
Turn time for express orders
The day when the order is placed/confirmed to the customer is counted as Day 0. For 1-3 day express orders the turn time is 13:00h CET (Monday to Friday) ( see special weekend orders ) Central European Time Zone (http://wwp.greenwichmeantime.com/time-zone/europe/european-union/central-european-time/) Example of counting production times for 3-days express order:
| by 13:00h CET | 13:00h CET | 13:00h CET | 13:00h CET |
|---|---|---|---|
| Day 0 | Day 1 | Day 2 | Day 3 |
| 24h production time | 48h production time | 72h production time |
Your order will be shipped on day 3 with your preferred courier. Transit time of the courier depends from the final destination of your order. For EU counties delivery time will be the next business day (by 9h or by12h - express options). Should you have any other request please call your Sales Representative.

Data FormatsODB++ ODB++ format makes possible shorter turn-around times because all information for the printed circuit board for manufacturers are clearly defined. ODB++ is a fully expandable ASCII data format with the following advantages: •All datas are included in one file. Nothing will be lost. •As many as desired attributes for the elements of the printed circuit board can assign to describe these elements. •There is a exact description of the graphical datas. No unnecessary filling of copper areas or pads with special forms which has to be exchanged by the pcb manufacturer. •A layer matrix that the parts list and the total structure of the plate defines. •ODB++ contains a CAD Netlist description on the basis those that Printed circuit board manufacturer can examine the electrical connections during the production process for their agreement with the original Design. •ODB++ contains a position table in that the layers names, the kinds of the layer the polarity as well as the sequence of the situations in the printed circuit board is defined. •ODB++ contains for the drill- and rout-layers the allocation which drill contact which layer. •Graphic notes can be attached according to the kind of a post it.
Gerber 274The Gerber format is a variantion of the conventional numerical control format. Of conventional Numerical control formats, like e.g. drilling data, it differs only by the selecting of d-codes. The data are arranged thereby in blocks what is a combination of the commands for the aperture selection, shutter mode (shutter open/close) and movement (X- Y-coordinates) The data are block-by-block processed. For defining the apertures on the CAM-System an aperture list will be necessary which described the form and size of the apertures. This should be usually entered manually into the CAM-System. This represents a substantial expenditure for the printed circuit board manufacturer.
| Example for an aperture file | Example for a Gerber file |
|---|---|
| D11 round 4 | G54D10* |
| D12 round 8 | X0000Y0000D02* |

Array/Multipanel
In case Array/sub-panel delivery of one PCB design is requested, please save the Gerber files with no more than 1 circuit image. Our engineers will make the step and repeat images according to your multi-panel technical drawing. - If the delivery is as sub-panel for ML is it O.K. to add copper balance on the frame of the panel on the Inner Layers - If the delivery is as sub-panel and the material thickness is below 0.8mm is it O.K. to add copper balance on the frame of the panel on all Layers. For multiple different PCB designs on one array/sub-panel please make sure ALL different designs to be set (pre-panelized) as one Gerber file with correct routing/V-scoring path file. NOTE: If designs are sent as separate files, we can create the multi-panel design at additional time and additional charge. Please take this information into the consideration in case your order is Express one.
