JOB CONTROL
DEFINITION
All new work taken on by PDS must be controlled, to make sure that
the customers brief is fullfilled, and that the job is costed and invoiced.
To make sure all these processes happen, a job control database is
used. This database is used to do the following:
 Allocate ‘Quote’ and ‘Job’ numbers
 Log the customer requirements
 Calculate quotations
 Measure the time taken to complete individual tasks
 Log total ‘man hours’ for a job
 Record Invoice Date and Due Dates so that invoices can be progressed.
This database in maintained with the aid of the Timesheet spreadsheet whose
purpose is to record daily time allocation
PROCEEDURE
Job Control Database
Quotation:
1. Take out a quotation number. This stars a new entry in the database
2. Select the customer from the pull-down menu, or add a new customer to
the Customer database, and then continue the above.
3. Fill out the section: ‘Details of Job Quoted for’, filling in the estimated
timings in the Column: ‘Time Est.’
4. In WORD, use ‘File, New’ to find the Quotation Template. Fill this out from
the information entered in the database. Print a copy of this and send it to
the customer through the post. (An electronic copy can be sent by Email).
Job Control
1. If the Customer accepts the quotation (and the PDS ‘Terms and
Conditions’), take out a Job number on the same database entry and fill in
the Order Date. A Customer Order number may also be added below if
available.
2. The Job will be in progress when sufficient information has been received
from the Customer.
3. As each section of the job is complete, fill out the actual timing. This
enables accuracy in future quotations and warning of cost / time over-
run.
4. When the job is complete, an invoice will be sent to the customer as soon
as possible, and the date of sending is recorded. The Due Date will be 30
working days from the date of Invoice.
5. When the Invoice is paid, the final entry is made for ‘Date Paid’. That Job
is now closed.
6. Any further work from the original remit, will require a fresh Quotation and
job entry.

DOCUMENTS AND NUMBERING
DEFINITION
Each new job will have a unique number which keys all the related documents
together. The process begins with the Quotation. There may be a number of
quotations which never tern into a job, however, since jobs are filed by
Project, unused numbers do not present a problem.
All quotations are files in the Quotation directory for future reference.
All Invoices and Receipts are Files under the Invoices directory.
All other documents are filed under the relevant ‘Project’ directory.

QUALITY CONTROL - DEFINITION
In order to ensure the quality of Designs done by PDS, the Quality Manual (in
Appendix 1 defines procedures which will be followed in order to ensure that
work leaving PDS is of a satisfactory quality, and that remedial action is taken
if there are errors.
Customers will ask PDS to design Printed Circuit Boards and mechanical
items of various sizes and complexity. Design tasks may vary from
mechanical component drawings and the digitising of very simple PCB’s
(where the minimum of documentation is supplied, and the minimum of
documentation is required to meet the customer requirements) to complex
Multilayer designs.
Whilst PDS had tried to put forward guides like the Design Check List, most
customers just want a straightforward design with the minimum of input from
themselves. As a result, the Design Check List will only be maintained as a
Guide with PDS recommends that it’s customers use when checking their
drawings and designs.
Quality Disclaimer:
Whilst every effort is made by PDS to produce designs and documents to the
very highest quality, it is incumbent upon the customer to check all designs
produced by PDS.
PDS will therefore not be held liable to faults, design errors; draughting errors,
manufacturing errors, non manufacuturability of any design done by PDS.
PDS will also not be held liable or responsible for any losses, consequential or
otherwise resulting from any draughting, drawing, incorrect component choice
or design errors done by PDS. This is explicit and implicit in the Terms and
Conditions publicised in Quotations and Invoices issued by PDS.
See Appendix 1 Quality Manual for details of quality processes and
procedures.

PDR DESIGN SERVICES
COMPANY MANUAL
PDS
Definitions of Quality guidelines; checks and methods used during the
design process:
Checking CAD Data:
The Bill of Materials (BOM): is checked against any BOM or component
listing supplied by the Customer.
Schematic:
 The Schematic is checked against any Schematic drawings supplied by
the customer, and any changes requested by the customer (by Email or
Fax).
 Design for EMC:
This includes Presence and position of decoupling; separation of Analogue
and Digital grounds and supply rails & adequate grounding of high frequency
devices.
 Design for Test:
The Customer should have made it clear whether Full Nodal; In-circuit or
Functional testing is required.
PCB Layout:
The PCB Layout is checked against any information; drawings; Gerber data or
requirements supplied by the customer.
Other parameters to check in the PCB Layout:
 Full Netlist check: back to the originating Schematic / Netlist.
 Continuity Check: based on the Schematic / Netlist.
 Spacing Check:
According to the Rules table set-up for this job. Some jobs will require
‘exceptions’ to make the customer aware that the job can still be
manufactured, but some rules table requirements have been compromised to
order to meet the customer requirements. E.G.Track to track or Pad to Pad
rules are showing an error on a fine pitch device which has tighter
requirements than the rest of the PCB.
 Design for EMC:
This includes Presence and position of decoupling; separation of Analogue
and Digital grounds and supply rails; adequate grounding of high frequency
devices; tracking of devices according to guidelines if supplied; tracking of RF
circuits in an appropriate manner etc.

PDR DESIGN SERVICES
COMPANY MANUAL
PDS
 High voltage clearance requirements:
Additional routing for air-gaps may be required. Spark Gaps may be needed –
grounded separately back to the PSU. No sharp track edges in the proximity
of the HV clearance areas. Final Checking of this will be carried out by the
Customer.
 RF Emissions:
Provision of RF screening or split plains; additional decoupling; R/C
terminations may be required to achieve emissions requirements.
Final Checking of this will be carried out by the Customer.
 RF susceptibility:
This may require the addition of grounded guard rings; additional plains;
screening etc. Final Checking of this will be carried out by the Customer.
 Design for Test:
The Customer should have made it clear whether Full Nodal; In-circuit or
Functional testing is required. Checks should be made to se that the particular
requirements have been met.
Final Checking of this will be carried out by the Customer.
 Design for Manufacture:
This includes all design rules supplied by the relevant PCB supplier, for
clearance; acid traps; track shrinkage.
 Design for Assembly:
This includes all design rules supplied by the relevant OEM; CEM; Assembly
house.
 Specification of the PCB for manufacturing.
This will include Layer stack-up; manufacturing laminates and chemicals (if
specified by the Customer); surface finishes etc.
Gerber Data:
When the Gerber data has been generated, the gerber should be imported
into a ‘gerber viewing’ tool e.g. Gerbtool; CAM350; ViewMate; GC Preview for
additional inspection.

RELEASE TO CUSTOMER
DEFINITION
This procedure documents the release of partially completed and completed
information to the customer. There is no differentiation between partially
completed or completed data. The end customer will be responsible for the
administration of all data received from PDS.
PROCEEDURE
All information releases to Customers are in electronic form unless specifically
requested otherwise. The electronic release of information will primarily be by
Email, in the form of a Zipped attachment, however, CD or 3 ½” disk are an
alternative.
Data which is released to the customer, is filed in the ‘Release’
directory of the Project file. Each release directory will be labeled RELddmmyy
(day, month, year), eg. REL020501. In this way all releases are recorded by
date. It is not expected that there would be more than one release in a day,
but should this occur, the addition of an index on the end should be sufficient
to indicate this.
The Release directory may contain one or more files. For ease of
sending the data, it is expected that the files will be in a compressed or Zipped
format.
Example:
REL010501
Deliverables:
Gerber Data
CAD files
Data Sheets (if applicable)
Related drawings (if applicable)

OVERVIEW OF QUALITY PROCESSES

PDR DESIGN SERVICES
COMPANY MANUAL
PDS
Quality Control
DEFINITION
This section details the procedure for Quality Assurance, to ensure that work
leaving PDS is of a satisfactory quality, and that remedial action is taken if
there are errors. The software is assumed to the AutoCad and PADS Power-
PCB and CAM-350 unless otherwise stated.
1) DESIGN
PROCEEDURE
To ensure that Jobs leaving PDS is of the highest Quality, the following
guidelines should be used. (see checking guidelines see page 14).
a) Checking CAD Data:
The Bill of Materials (BOM): is checked against any BOM or component
listing supplied by the Customer.
Drawings:
 The drawing or drawings are checked against any drawings sketckes or
diagrams supplied by the customer, and any changes requested by the
customer (by Email or Fax).
Schematic:
 The Schematic is checked against any Schematic drawings supplied by
the customer, and any changes requested by the customer (by Email or
Fax).
PCB Layout:
The PCB Layout is checked against any information; drawings; Gerber data or
requirements supplied by the customer.
Other parameters to check in the PCB Layout:
 Full Netlist check: back to the originating Schematic / Netlist.
 Continuity Check: based on the Schematic / Netlist.
 Inner and outer layer conectivity and continutiy.
 Spacing Check:
According to the Rules table set-up for this job. Some jobs will require
‘exceptions’ to make the customer aware that the job can still be
manufactured, but some rules table requirements have been compromised to
order to meet the customer requirements. E.G.Track to track or Pad to Pad
rules are showing an error on a fine pitch device which has tighter
requirements than the rest of the PCB.

PDR DESIGN SERVICES
COMPANY MANUAL
PDS
2) DATA OUTPUT
a) CAD / CAM Software Installation Procedure (Power-PCB)
The CAM Device dialogue box, under the section 'Advanced', will have the
following boxes ticked:
Units: English
Digits: L=3, T=5
Coordinates: Absolute
Zero Suppress: leading
Output format: RS274X
Fill & Macro: Fill Mode: MUST NOT BE TICKED, Use Aperture Macros:
Ticked
All other areas are Default.
b) Gerber Data:
When the Geber data has been generated, the gerber should be imported into
a ‘gerber viewing’ tool e.g. CAM350 (or alternatively: ViewMate; GC Preview).
Layers of data may have to be ‘aligned’ in the software.
c) Typical checks would be:
 All data should be present to facilitate the manufacture of the PCB. If
necessary a separate Mechanical drawing should be translated into gerber
format, to include mechanical requirements like: internal routing details,
break-off details or panelisation requirements.
 Data in RS274x format
 Pad and track sizes are as specified in the PCB layout.
 Alignment of ‘peelable’ masks.
 Legend infringements onto solder pads.
 Correct reproduction of ‘copper pours’ and automatic thermal or electrical
plain generation.
 Any other details which are manually constructed in the CAD, for electrical
or manufacturing purposes.
d) Additional Checks:
All Gerber data generated by PDS will be inspected using the following
method, prior to being issued to the Customer or Production:
i) Gerber will be inspected as 'electrical layer pairs'. This is applicable to
2 sided and multilayer PCB's. For multi layer PCB's, this will mean
either 'signal to ground' or 'signal to VCC' planes. Objective: To search
for pad and vias connected to the EMC planes by copper flooding, and
not by thermal relief's, which are not specified in the original CAD.
ii) Exceptions to this rule. For 'ultra miniature designs where 'via flood-
over' is deployed as part of the design. In this case, this should be
checked with respect to the original CAD Data.
Objective: To search for pad and vias connected to the EMC planes by
copper flooding, which are not specified in the original CAD.

PDR DESIGN SERVICES
COMPANY MANUAL
PDS
3) MANUFACTURERS FRONT END INSPECTION:
The purpose of the PCB Manufacturers ‘Front End Inspection’ is to check for
manufacturability of the PCB prior to panelisation, and the generation of the
Drilling and Routing data. This process cannot be relied upon as a backstop
for problems. The Gerber Front End department is usually under pressure,
especially for short delivery times.
