SMT Assemblies Why Solder Paste Inspection?
The majority of SMT defects occurs during the solder paste printing process. According to data from SMTA (The Surface Mount Technology Association), 74% of defects in PCB manufacturing process are related to solder paste.
Assembly Process Defect Chart
Why??Is Printing so Important
1. Production must be more FLEXIBLE.
2. Mixed technologies, on the same board.
3. Limited space, Assembly density 4. Budget reductions
5. Quality demand6. No rework permitted
Processes continue to be challenged
If that werent enough…….
Miniaturization
The concept is
clear….The SMT
printer Process needs

Since Q32013 Sales Started
• ALL TopLINE Nanos, “Cobra HD” vs “COBRA 3.0 y TX”– Sensative to stencil wash– Wearing of the “COATING”– Aplication type “Coating”– On time Delivery– Componentes– “Nano” waste management– Outperforms any Nano, Eform, Ni stencil
– COBRA will Last the life of the Stencil!!!!

Customer Feedback
NEW Cobra SS
Standard SS Stencil
GDL Site Increased ICT Yield 60% to 75%. Excellent paste release After Introdcing COBRA
GDL Site We compared COBRA with E-Fab stencil. COBRA had a
better release of solder paste,we reduced problems in our printing process
Customer Feedback
Automotive Customer Requirement: Use Eform Std as minimum requirmentsThey had 3D SPI inline
Volume MeasurementsCpK >/= 1.6
Std Dev </= 816 mil pitch QFP
EFab
COBRA 3.0
This denotes an effect caused by the USC while using EF but did not affect COBRA print quality
The SPC sine wave is representative only
Final results: Efab 100% of established SPI volume
Cpk: 1.56Std Dev= 11
COBRA 115% Volume compared to EfabCpK: 2
Std Dev= 6
Note: NOT even the underscreen cleaners elements interfered with the COBRA print quality
Customer Feedback
We further Challenged COBRA
We Needed to Push COBRA….here is our story
Note: We have more customer feedback
What we Did, June 2014
• Created a test vehicle, representing current assembly challenges, for our customers
• Setup an SMT printer, Fully automated• Programmed Solder Paste Inspection system,
fully automated• Made one common stencil design, IAW
industry standards…..NO special designs
We further Challenged COBRA

• Reduction in Cost– Lasts the Life of the Stencil– Helps reduce Consumible
consumption• Improves AR Performance
– More productivity• Stencil Life Warranty
– COBRA will NOT come off, Under Standard SMT Process Practices
• Improved OTD– Made in Local sites
• Local design Support….over 20 years
• Local Eng Printing Support…..over 20 years
• We will work with all customers to support their process.
