It happens around us whatever you notice or not
On year 2013, Hitachi elevator free fall due to
defected board in China, a lady was injured in
this event.
On year 2013, GM recall 380,000 vehicles due to
defected engine control board.
Due to abnormal behavior of PCBA, Taiwan high
speed train lost power on year 2013.
Major reason of AirAsia QZ8501 crash on year 2014
is a cracked solder joint on PCBA.
On year 2013, Chrysler recalled gt470,000 vehicles
due to defected board.
On year 2014, Mitsubishi recall 115,000 cars due
to defect board of light switch.

Are you always willing to stay with those issues?
  • Quality/reliability defects

No thermal consideration, leads to cold solder,
impact solder strength
Silkscreen cross brings build and rework risk
Stage Defects Remark
Design No thermal consideration Annual ring small Silkscreen error Silkscreen incomplete gt30 PCB design comes with problem.
Manufacturing Short Open Tombstone Cold solder Void gt60 defects could be found prior to build
Post-sales Solder joint crack Solder joint peeloff Repair rate for consumer product 537 in initial 3 years
Nonwetting
Tombstone
Bridge
Void
Via is too close to parts, it leads to poor
solder joint, impact solder joint strength
Crack risk
IPC research 80 defects could be found and
resolved at NPI stage.

Customer Testimonials
We have been impressed with the product
capabilities, their communication and commitment
to supporting their products is truly world
class.
Vayo tool is a very intuitive and user-friendly.
You can match parts and pds visually and new pd
can be created easily. Part Data Editor and
Parts Verification ensure every location has
correct part, size and orientation.
Vayo tool has been extremely useful for us in
identifying assembly issues much ahead of the
actual assembly process. This has drastically
reduced holdups in the production line,
increasing our productivity.
From years of experience with DFT and CAD SW's,
VayoPro-Test Expert is the best. It is fast,
accurate and easy to use. Its DFT report is very
comprehensible for our customers.
We started with Vayo at year 2009 and has not
been turning back since then. What differentiate
Vayo from the rest is their willingness to listen
to customers needs with fast respond.
I was impressed by Vayo NPI tool, it is really
world class solution in the industry!

CHIA Kar Lin Head of Innovation Centre
Accelerator allowed us to reduce a lot the
quantity of mistakes in the projects and the time
required for their preparation.
by introducing Vayos intelligent software tool
it is now possible for operators to perform data
conversion requiring little skill, while reducing
the work time required to a fifth of what it was.
From the selection of Vayo solution on the year
of 2007, we are able to support these data source
whatever we receives what kind of data from new
customer, and then quickly complete placement
programming.
With VayoPro-Test Expert solution and great
support of Vayo team, we could accelerate our
product review for DFT (ICT/Boundary).
Communication is important for every filed, good
conversation shall bring joyful experience, Vayo
is such company we worked with!
The accelerator function could help us a lot on
component placement orientation, we don't need to
do mapping Gerber file and check placement
orientation one by one any more.

DFx is must capability for every electronics
company
10
Why DFx predict/solve process issue
IPC research 80 defects could be found and
resolved at NPI stage.
  • Predict defect opportunity, increase
    manufacturing quality and reduce cost

With DFx consideration Increase process
difficulty steps rapid solder/assembly
defects increase rework rate and work loading
lower work efficiency and increase manufacturing
cost
11
Why DFx Improve product reliability
Medical/automotive/military/aerospace/ product
require high reliability
  • Improve reliability, reduce repair rate, protect
    brand reputation.

Increase PCBA lifecycle
Stability of consumer electronics products
impacts brand loyalty and service cost.

Sample DFx issue material not match PAD design
  • Impact
  • Stop production, waste product line resource
  • Delay shipment go-to-market

Package not match
Package not match
Package not match
Missing via, small copper size
25
Sample DFx issue components too close
  • Impact
  • Require high precise equipment
  • Risk of assembly conflict
  • Difficult to rework

26
Sample DFx issue Via distance to pad
Impact More via on boards, it shall be more easy
to bring short, bridge, and insufficient solder
issues.
Good design
27
Sample DFx issue annual ring design
Annual ring too small, even missing
Via offset to pad
Impact Easy to cause weak structure lead to
crack/ broke malfunction in severe usage
conditions.
28
Sample DFx issue risk for via under component
Impact May cause bridge/short when PCBA goes
through wave process.
29
Sample DFx issue Via under BGA pad
Impact via in BGA pad, it might lead to weak
solder joint strength because of void. It shall
impact product reliability.
30
Sample DFx issue BGA pad design
Solder mask defined pad, it shall easily cause
the root of solder joint crack especially in
frequently shock environment.
31
Sample DFx issue no thermal consideration
Good design
Poor design
Poor design
Impact It might cause tombstone if there is no
thermal consideration. Or it might cause
insufficient solder for PTH parts, and then
impact solder joint strength and product
reliability.
32
Sample DFx issue PTH part to mask strip
Poor design
Impact PTH part approach mask strip too near,
easily cause solder issue like short.
33
Sample DFx issue poor test point design
TP size impact contact of probe, then impact
faults reject rate of test.
34
Sample DFx issue poor silkscreen design
No polarity mark
Cross of part reference name
  • Impact
  • Wrong polarity during assembly
  • Replace with wrong material during rework

35
Sample DFx issue no local fiducial for
fine-pitch parts
Impact Brings offset risk during assembly
Good design
36
Sample DFx issue Orientation of part pass
through oven
Poor design
Good design
Impact Part placement orientation shall be
consistent with wave process, otherwise it may
casue bridge.
37
Sample DFx issue BOM content error
DFM Expert perform intelligent check of BOM
content, report any quantity mismatch error.
Impact Component mismatch may leads material
shortage for the work order, which leads to
production stop, waste equipment resource Or
cause excessive material purchasing and extra
inventory.
38
Sample DFx issue Alternative part analysis
DFM Expert compare dimension between alternative
part with primary part, and alter upon big size
difference.
Impact Big size difference between alternative
part with primary part may cause assembly
problem, solder joint defect or poor reliability.
