When 16 GT/s Demands More Than Just a Slot

PCIe Gen4.0 doubled the per-lane data rate from 8.0 to 16.0 GT/s. That jump places real pressure on every component between your CPU and add-in cards, and the slot connector is no exception. Signal reflections, crosstalk, and insertion loss that were tolerable at Gen3 become deal-breakers at Gen4.

CONSHARE engineered this 98-pin slot connector for exactly that environment. It is a through-hole (DIP) mounted connector featuring a post — the structural guide feature above the contact area that helps add-in cards seat correctly and reduces misalignment during assembly.

What the Post Actually Does for You

The post isn't a cosmetic detail. On high-density boards where technicians assemble and re-seat cards repeatedly — server farms, test benches, prototyping labs — misalignment during insertion ranks among the top causes of bent contact pins and intermittent signal failures. The post functions as a physical guide rail, correcting card angle before contacts engage. Fewer damaged pins, fewer field returns.

Material and Plating: Choices That Show Up in Yield Rates

LCP Insulator — Not Just "High-Temperature Plastic"

The insulator body is molded from LCP (Liquid Crystal Polymer). That selection is deliberate:

• Dimensional stability across reflow and wave soldering — the connector body goes through the oven and doesn't warp

• Low dielectric loss at high frequencies — directly supports Gen4 signal margin

• Moisture resistance — mechanical and electrical properties stay consistent through humid shipping and storage

For a connector sitting on a motherboard through years of thermal cycling, LCP prevents body creep, cracking, and contact geometry drift.

Gold Plating at 15 Microinches — the Practical Middle Ground

The contact area carries 15μ" gold over nickel. This thickness is chosen with intent:

Fifteen microinches gives enough gold to survive the repeated card swaps that happen during server maintenance and testing — without paying for test-grade gold. It's where reliability meets cost efficiency.

PCB and Pin Geometry: Built for the Manufacturing Floor

2.0mm PCB — Rigid Enough for Real Assembly

The recommended PCB thickness is 2.0mm. Not the thinnest available, and that is the point:

• Through-hole barrels gain sufficient wall thickness for reliable DIP solder joints

• The board resists flexing during card insertion — push an add-in card home without PCB bowing

• Thermal expansion mismatch between connector body and board stays within manageable limits

3.1mm DIP Pins — Through-Hole That Holds

DIP pins measure 3.1mm, designed for through-hole soldering. Surface-mount pins save assembly steps but sacrifice mechanical retention. Through-hole DIP pins lock the connector physically to the board — critical for a slot that receives an add-in card under insertion force. No solder paste on an SMT pad matches the pull strength of a through-hole joint.

Is This the Right Connector for Your Design?

CONSHARE Production Standards

Quality Control on Every Batch

Each production lot passes through:

• Contact resistance testing — catches plating defects before shipment

• Insertion / withdrawal force measurement — grip within spec, not too loose, not too tight

• Visual + AOI inspection — pin coplanarity, body integrity, post alignment

• Solderability sampling — verifies pin finish accepts solder cleanly

Lead Time and Customization

Standard production runs ship in 2–3 weeks for volume orders. For design teams needing changes beyond catalog spec, CONSHARE can adjust:

• Gold plating thickness (10μ"–30μ")

• Pin length and DIP tail geometry

• Packaging format (tape & reel, tray, tube)

• Marking and labeling

Reach out early in the design cycle — accommodations are far easier before tooling locks.

Questions We Hear from Buyers

Will this work with Gen3 add-in cards?

Yes. Gen4 slots are backward compatible. A Gen3 card seats and functions correctly — you simply won't use the full Gen4 signal margin.

What's the rated insertion cycle life?

With 15μ" gold, expect 50+ reliable insertion cycles. Test fixtures needing hundreds of cycles should ask about 30μ" plating options.

Do you supply full mechanical drawings?

Yes. Contact CONSHARE directly for the complete drawing set including recommended PCB layout, keep-out zones, and reflow profile guidance.

What is the minimum order quantity?

MOQ depends on configuration. Share your annual volume estimate and we'll structure pricing accordingly.

Can you match a specific customer qual spec?

In most cases, yes — particularly for plating thickness, packaging, and dimensional tolerances. Send the spec sheet and we'll confirm compatibility.
