OEM Integration
In order to integrate the 3M
TM
RTE6701-OEM Passport Reader Module into your equipment you need to
consider a number of design issues and ensure that your manufacturing process is appropriate. This section
helps you through some of these questions.
Having tested the Module in a standalone configuration and ensured its suitability the first task is to design a
document guide, see the next section for more detail. This will include the mounting of the read head to the
guide and the retaining of the glass window.
The mechanical mounting of the PCB is next – the key point being to keep the cable from J2 as short as
possible, see below for more information. Be careful to ensure that the 3 way head illumination cable reaches to
J4.
Design a USB to host cable to suit your requirements noting that this may need a ferrite(s) to reduce
radiated/conducted EMC emissions. Determine whether you wish to use a separate power input on J5 rather
than USB supplied power (see
section 6
).
The product then needs testing to your required standards. See “
Appendix A – EMC Compliance
Techniques
” for more information.
Ensure that your manufacturing process is aware of the ESD precautions required and that they use the correct
read heads with PCBs where that is an issue, more details below.
In summary assembly procedures, control of ESD, cabling and connector choices can all
contribute to significant improvements in product reliability and prevention of
“in the
field”
failures. These recommendations will greatly reduce costs due to part failures and
provide increased end-user confidence in your product
.
7.1
Read Head Manufacturing Procedures
The read head is a compact electro-optical assembly with a 10-way dual row 0.1-inch pitch connector for the
camera assembly. In order to minimise the cost and size of the head, the camera is connected directly to these
pins.
The camera electronics are sensitive to damage from static electricity. It is
therefore essential that proper electro-static damage (ESD) control measures be
put in place when assembling the head into OEM equipment.
The read heads are supplied in anti-static packaging and should be unpacked as
close to the assembly area as possible.
Operators should wear anti-static wrist straps and assembly should take place at
a properly grounded anti-static environment.
