SCOPE The purpose of this specification is to define the requirements and specifications applicable to the manufacture and testing of printed circuit boards supplied by Tecnometal Srl. This specification defines the requirements and conditions of supply, production and acceptance of printed circuit boards, without prejudice to different directions from the customer. For any aspect not reported in these specifications, are subject to the conditions of acceptability provided for by the IPC A-600 Class 2 standards.

REFERENCE STANDARDS IPC A-600 - Class 2 (On request shall apply the Class 3)

DOCUMENTATION The documentation concerning the printed circuit boards production is provided by the client who remains the owner. The documentation will be returned to the customer at his request. Tecnometal, as a result of the feasibility study, if necessary and subject to authorization by the customer, will be able to edit the customer’s files.

TOOLING The tooling realized by Tecnometal and needed for the printed circuit boards production, are of Tecnometal property.

PRICES The prices are indicated in the Tecnometal order confirmation sent to the customer.

RESPONSABILITY Tecnometal ensures the circuits electrical functionality. The circuits must be duly preserved by the customer in environments with temperature and humidity controlled in accordance with IPC. 1601. Any non-compliance must be reported to Tecnometal within 12 months from manufacture date. In the case where products non-compliant should be confirmed, Tecnometal will substitute them or repairing them according to the procedure laid down by point 3.8 of this Terms of Delivery. In case that it is not possible replacement or repair of non-compliant products, Tecnometal indemnify the customer of the price paid by the latter only for non-compliant products without any direct and/or indirect additional cost.

3.9 SOLDER MASK TOUCH UP Tecnometal undertake touch up on both sides taking care of solder mask property and PCB aesthetic appearance.

3.10 LOGOS In order to unsure the PCB traceability, TECNOMETAL will apply the following logos provided by Tecnometa S.r.l.:

- TECNOMETAL LOGO - Production DATE - “R” RhOS compliance identifies

If the customer specifically asks not to affix logos for traceability, in case of any non-compliant products, not being able to identify their products, Tecnometal shall not be liable as provided in paragraph "WARRANTY AND LIABILITY '" on page 2 of this Terms of delivery.

NOTA BENE Tecnometal recommends to store the printed circuits, as well as furnished in packages by 25 PCBs wrapped with "bubble wrap" and vacuum heat-shrinkable (not absolute), at a temperature between 20 and 22 ° C and relative humidity lower than 50%.

After 3 months from the PCB production date is recommended to execute the "baking" for the residual moisture removal.

Temperature and time are established according to the type of finishing (baking NOT executable with OSP, chemical tin and chemical silver finishing) and the laminate thickness;

We recommend to execute the baking with properly stacked and aligned PCB. Don’t move the PCB until they’re cooling.
