Design requirements

- ad 1): Company name “ASM AS”

- ad 2): The item number with FS (functional version) is specified in the manufacturing documentation.

- ad 3): The manufacturing ID consists of:

- Factory code: Is specified by Purchasing

- Alphanumerical date code: Defined in Subsection 9.6.4

- Serial number: To be specified by suppler on specific request of customer only

Layout in case of restricted space

The 2D coding shall be implemented in Data Matrix ECC 200 according to ISO/IEC 16022.

The data string of the code has the following information content (without spaces):

The blank zone BZ shall be designed as a function of the barcode resolution X at  2X.

The resolution is determined by the application and must be adequate for the labeling and reading technology used. The

resolution according to ISO/IEC 16022 is X  0.25mm. Higher resolutions are possible but are subject to legibility testing

by the customer.

The width W and height H of the barcode depend on the resolution X and the number of characters in the data string.

This yields e.g. the following results:

− for a resolution with 6 dots and 53 characters, a barcode size of 6.6mm

− for a resolution with 4 dots and 53 characters, a barcode size of 4.4mm

− for a resolution with 4 dots and 15 characters, a barcode size of 2.4mm

9.6.3.3. Electrical / electronic assemblies (printed circuit boards)

Labeling methods:

For the entire assembly: Adhesive label

For the board: Print, engraving, laser printing, in Cu (in layout); other methods as agreed with ASM

AS. The location of the labeling is specified in the component mounting diagram (see

example below).

The UR logo, the manufacturer logo, the board type and the flammability class

according to UL 94 must be etched on the board as part of the layout.

The locations of the labeling are defined in the component mounting diagram of the printed circuit board. Each location is

identified with a letter code (A, B, C) and an outline.

In case of difficult space conditions, the contents may be distributed among several locations (partial labeling B1 .. Bn).

Fully designed labeling layout for printed boards (A = Identification label)

- ad 1): Company name “ASM AS”

- ad 2): The part number with FS (functional version) is specified in the manufacturing documentation.

- ad 3): The serial number must be specified if unique traceability is required.

- ad 4): The alphanumerical date code is defined in Subsection 9.6.4.

- ad 5): The factory code is specified by Purchasing.

In case of difficult space conditions, the contents may be distributed among several locations (partial labeling

A1 .. An).

Externally developed standard printed boards

- ad 1): The company name (currently ASM Assembly Systems) is specified in the order text.

- ad 2): The item number with FS (functional version) is specified in the manufacturing documentation.

In addition to the labeling shown, the supplier must mark these products with his manufacturer name or manufacturer

code, type designation, serial number and/or the manufacturing date.
