Cam Master, Fix Master, Probe Master from Lavenir
Technology
7: How

Calculation.
8: What
are typical Dielectric Spacing for 8 and 10 mil trace
width for 50 Ohms MicroStrip?<top>
- Ex: Fr-4, 4.5 Dk: 8 mils trace: Dielectric between
signals and Plans are 5 mils.
- 10 mils trace: Dielectric between signals and plans
are 6 mils.
9: What
type of Solder mask do you use?<top>
- Liquid Photo Image (LPI) Solder mask is standard.
- Other solder mask available on request.
10:
What is Bed of Nails Testing and how is it performed?<top>
- Location of all components is extracted in the
form X and Y coordinates and a NC drill file is
created. Test plate fixture is drilled and is assembled
on a standard bottom plate with holes located at
100 mil centers. At each point of the component
hole location a pin is dropped. All the pins are
inserted. The fixture is placed on the test machine,
a board is placed and all the connections and isolations
are learned. All the other boards are tested with
the first board as a reference. This test ensures
that all boards are identical
11:What
is Clamshell Net list testing and how is it performed?<top>
- Clamshell Net list testing is similar to bed of
nails testing. This type of testing is used if the
board has components on both sides. This test is
performed using fixtures for both sides simultaneously
and the Net is generated direct from the Gerber
Data using one of CAD Software.
12:What
is Flying Probe testing and how is it performed? <top>
- As the fixture costs are very high, a fixture
less type of testing is used. The test machine has
probes, normally 4 to 16 probes on both sides that
move to each location of the net and checks for
opens and shorts. This type of testing is more economical
for small prototype runs. For quantities of more
than 10 boards with more than 2500 nets, fixture
testing (bed of nails) is faster. We extract the
netlist from your Gerber Data or using your IPC-356D
format to test 100% Short and Open.
13:How
do I send a request for quote (RFQ)? What files do I
need to send?<top>
