SOCKETS DE TEST

Avantages du Dyno :

• Une solution unique et fiable pour les contacts étamés ou en NiPdAu

•Contact monolitique• Frottement contrôlé à Virer • Pression importante,Compression avec frottement/autonettoyage du Compression avec frottement/autonettoyage du

pad

• Grande durée de vieFrottement répétable et maitrisé offrant une

résistance de contact faible et constantejusqu’à +500,000cycles

• Grande Plage de temperature De -50°C à 150°C, jusquà 160°C

SOCKETS DE TEST

Avantages du Dyno :

Maintenance Simple :L’élastomère est utilisé pour la mise en

position des contacts mais ne participe

pas à son effet ressort.

Haute intensité :Jusqu’à 5A Continu par contact

( à 80°C, 0.5mm pitch contact)( à 80°C, 0.5mm pitch contact)

Coût :Comparable à la technologie Spring

probe

Durée de vie plus élevée

Moins de maintenance

Case Study # 1

– Boitier: 32QFN, 7x7, P 0.65mm, 8-bit Microcontroller.

– Test frequency: <100MHz at 40mA per I/O

– Solder pad material: Matte Tin

– Platform: Dual sites on MT9510

Results

Tested >1,550K at three temperature (room, -45ºC HOT 130ºC/155ºC, still using the Tested >1,550K at three temperature (room, -45ºC HOT 130ºC/155ºC, still using the original Dyno pins since start of the evaluation.

Socket being compared with main competitor, comparable yield with reduced cost of the ownership and maintenance downtime.

Dyno Advantages

Better performance Customer decided to extend the Dyno contactor also to the QFP family (@155ºC)and to other product such as: 64QFN Single Site, 64QFN Dual Site, 32QFN Dual Site and 32QFP Dual Site.

Case Study # 2

– Package: 32QFN, 0.5mm pitch,

64QFN, 0.4mm pitch,

– Test frequency: 10 MHz, lower current

– Solder pad material: SnBi

ResultsResults

Stable Yield, customer appreciated the reduced mark/nodamage on board pad.

Dyno Advantages

One solution is addressing several type of material.

Case Study # 3

– Package: 20QFN, 5x5, P 0.5mm

– Test frequency: 10 MHz, lower current

– Solder pad material: NiPdAu

– Platform: Seiko- Epson 7000, Quad sites

ResultsResults

The feedback from customer that higher spring force means better test yield and the pins are simple and easy to maintain. But some sort of sharp cleaning tool is required to help removing debris from the pins as well as the pin slots.

As per customer feedback, the Dyno contact last ~ 150K insertions with the old socket design.

Dyno Advantages

Case Study # 4

– Package: 64QFN, 8x8, P 0.4mm, Data Transfer.

– Test frequency: <200MHz at <300mA per I/O

– Solder pad material: Matte Tin

– Platform: NS6040 handler, quad sites testing

ResultsResults

As per customer feedback the yield is more stable than similar sliding contact solution.

Average: Dyno -92.33% Competitor Y 86.92%.

Customer is currently at 65.5K/per site.

Dyno Advantages

Better First pass yield, CRES is more stable due to the higher force of the Dyno solution (40grf @0.4mm pitch)

Case Study # 5

– Package: 32QFN, 5x5, 0.5mm pitch

– Application Power device, 100MHz, 200mA, 25 deg C

– Solder pad material: NiPdAu

– Platform: Turret type Bowl feed handler

– Remark: Replaced spring probe socket

ResultsResults

Customer was struggling for the QFNs testing as devices are mostly NiPdAu plated. Spring probe solution never surpassed the life cycle of greater than 100K insertions.

Dyno Advantages

Customer currently reached 500,0000 cycle, Yield starting to drop so they will probably replace the contact.

Lifetime 5x spring pin solution.
