RFQ / Order Documentation
Quotation requests and orders must be accompanied
by documentation that defines the board to be tested. There are three general areas
of needed information; board documentation, device documentation, and sample boards.
The items needed, when they are needed and why
they are needed can be somewhat confusing. The following table is intended to
clarify these documentation requirements.

| Schematics |
The Schematic is used
for circuit description entry, to determine testability, and for program and fixture
debug. |
YES |
YES |
| Assembly Drawing |
An assembly drawing
showing the component layout is needed to identify fixture design considerations and to
locate probe points. |
YES see
note 1 |
YES |
| PCB Drawing |
The PCB drawing should
show dimensions and hole locations. It is used for reference. It can
often provide answers pertaining to the boards physical characteristics. |

| Parts List |
The bill of materials
(BOM) should show component reference designators, values, tolerances, and commercial part
numbers for all devices. |
YES |
YES |
| Cad File(s) |
Cad files can be either
a single or a multiple of output files depending on the cad system used. The
Cad file contains identity and coordinates of components, pins, pads, required vias and
signal lists. This file is used to generate the in-circuit input files.

| Data Sheets |
Data Sheets describe the
operation of devices installed on the circuit board. They are used to create
test vectors for custom devices, if vector testing is preferred by the customer. |
NO see
note 1 |
YES |
| PLD Files |
These files are
programmable logic device files. They are required to generate test vectors if
vector testing is preferred by the customer. Required
PLD files will be specifically identified by TSS at the time of quotation. |
NO |
YES |
| BSDL Files |
Boundary Scan
Description Language files are required if boundary scan testing is preferred by the
customer. They are usually available from the World Wide Web site of the
device manufacturer. |
NO |
YES |
| ISP Files |
In System Programming files allow tests to be
developed that program ISP capable PLDs and FLASH memory devices. Required
ISP files will be specifically identified by TSS at the time of quotation. |

| Bare Board |
An unpopulated board is
used for reference. It can help to determine probe locations and fixture
damming. It can be used for digitizing when drill files are not
available. It can often resolve questions pertaining to the schematic. |
NO see
note 2 |

note 2 |
| Assembled Board |
Five known good
populated boards (one is the minimum requirement) should be provided. The
board(s) should be mechanically and electrically correct and agree with the other provided
documentation. The board(s) are used for fixture layout and debug of both the
program and the fixture. |

1) The quote can be prepared without this item. However the quote can
be prepared more quickly and accurately if this item is available.
2) This item can be considered to be insurance as it may solve problems or
provide answers to questions that would otherwise cause delays. It may never
be needed, but it is prudent to provide if available.
3) The absence of this item can have significant impact on cost and delivery.
The test can be developed without this item, but it should be made available if at
all possible.
