Large Format & High Pin Count Sockets
5,000+ Pins. Zero Contact Failures. Testing today’s massive AI processors and Data Center CPUs requires more than just high speed—it requires mechanical mastery. Our high pin count test sockets are engineered to maintain uniform contact force across arrays exceeding 5,000 I/O, even when dealing with package warpage and substrate irregularities. We combine high-strength alloys with floating alignment plates to ensure every pin hits its target, from the center die to the corner BGA.
LARGE FORMAT & HIGH PIN COUNT CONFIGURATIONS
Testing today’s massive AI processors and Data Center CPUs requires more than just high speed—it requires mechanical mastery. Our high pin count socket architectures utilize floating alignment plates and high-strength stiffeners to maintain uniform contact force across arrays exceeding 5,000 I/O.

Overview
KEY FEATURES OF OUR LARGE FORMAT SOCKETS
- Floating Plate Technology: We utilize independent floating alignment plates that move with the device, compensating for package bow and twist to prevent “corner opens” on large BGAs.
- Mechanical Reinforcement: For high-force applications (200+ lbs total force), we design custom backing plates and board stiffeners to prevent your PCB from flexing and breaking BGA traces under the socket.
- Precision Alignment: We achieve 35-micron alignment accuracy across large fields, ensuring probes hit the center of 0.4mm pads even on the largest 70mm packages.
- Hybrid Pin Maps: We can populate the array with a mix of RF probes (for SerDes lanes) and High-Current probes (for VDD rails) to optimize performance vs. cost.
- Damage-Free Handling: Our lids feature “soft-touch” compression stops to apply massive force without cracking fragile bare dies or crushing solder balls.
VERIFIED PERFORMANCE & RAPID DELIVERY
FEA Simulation
We predict the bend.
Before manufacturing, we perform Finite Element Analysis (FEA) to simulate the mechanical stress on your PCB, ensuring the socket force won’t damage your board.
Precision Machining
Large Format CNC
Our Massachusetts facility is equipped to machine complex, large-format socket bodies and stiffeners with tight tolerances that overseas mold-shops can’t match.
Reliable Delivery
Optimized Supply Chain
We manage logistics locally to minimize bottlenecks. Custom large-format fixtures are typically deliverable in 6-7 weeks.
GET A FAST & ACCURATE QUOTE
To speed up your mechanical simulation (FEA) and quote process, please have the following ready:
- Device Package Drawing (POD): PDF/DXF format (Must show full ball map).
- PCB Thickness: Critical for designing the backing plate screws (e.g., 93 mil, 120 mil).
- Backside Topography: Are there capacitors directly under the socket on the bottom of the PCB? (affects stiffener design).
- Lid Type Preference: Do you need a heat sink lid or a flat compression plate?
Do I need a backing plate for a 2000+ pin socket?
Almost always. With typical spring forces, a 2000-pin socket can exert over 100 lbs of force. We design custom backing plates (stiffeners) to distribute this load and keep your PCB flat.
How do you handle package warpage?
We use a combination of “floating” guide plates and high-compliance probes (long travel) to absorb the Z-height variations caused by package warping during thermal cycling.
Can you replace existing elastomer sockets?
Yes. Our spring probe sockets can often be designed to fit the same mounting holes as elastomer sockets, offering higher durability and lower contact resistance.
