Card Edge Connector
Industrial, IT Datacom
Every DDR4 board — server, workstation, industrial PC — stakes its memory reliability on a part that rarely gets a second look during design review: the DIMM socket. It looks like a commodity component. In practice, a socket with marginal terminal coplanarity or a thin gold finish converts directly into first-pass yield losses on the assembly line and intermittent memory errors in the field. This 288-pin DDR4 socket from CONSHARE is engineered around those failure modes, not around a price point. The result is a part you can specify, board after board, without thinking about it again.
A 288-pin DDR4 module means 288 contact points, arranged as 144 independent contacts per side. That is 288 separate opportunities for a marginal joint, a weak contact, or a plating defect — and most of them will not show up until the board is already built.
When they do fail, the failure signature is ugly. Boards that pass a bare-board test start dropping memory training at the system level. A server reboots at random. A burn-in rack loses a slot. Each of these sends your team back to rework, retest, or field replacement — all of which cost more than the socket itself did.
The socket decision is made once and lived with for the life of the product. Spending the extra effort on the connector is the cheapest insurance available to a board design.
Feature | What it does on your board |
|---|---|
288 contacts, dual-row (144 per side) | Every signal gets its own independent contact — no shared or stitched grounds, cleaner signal paths for DDR4 speeds |
30 µ" gold on the contact surface | A heavy plating layer that holds up through repeated insertion and humid, corrosive environments; most consumer-class sockets run significantly thinner |
PA66 housing, dark blue (293C) | High-temperature nylon that stays dimensionally stable through lead-free reflow; the dark pigment gives clean contrast for AOI inspection |
White latch | A high-visibility mechanical check — operators and AOI systems can confirm the module is fully seated before the board ships |
DIP 2.5 mm through-hole tails | Solder joints with real mechanical strength, in a pitch that routes cleanly on standard DDR4 layouts and survives vibration far better than SMT |
None of these are marketing claims. They are choices that show up in measurable ways: fewer cold joints, fewer returned boards, longer service life.
The difference between a good socket and a marginal one is almost invisible on paper — and very visible on a wave solder line.
If the tails do not sit in the same plane, some pins solder perfectly while others stand slightly proud of the pad. The result is an intermittent connection that passes a continuity test but fails in the field. CONSHARE holds terminal geometry to tight tolerances precisely so this does not happen; every tail is designed to sit flush, every row to mate evenly.
A socket this long spans a large portion of the board, and it must survive the thermal shock of soldering without warping. PA66 keeps its shape through lead-free process temperatures, so the contact geometry you approved in the datasheet is the geometry that lands on your board — not a warped approximation of it.
A half-seated module is a common cause of "mystery" memory failures, and the white latch is the cheapest fix: it makes the seated/not-seated state unambiguous at a glance.
This socket is at home anywhere a DDR4 module needs to be field-replaceable or serviceable:
Servers and workstations — where memory is expected to be swapped, upgraded, and reseated over a machine's life
Network equipment — switches, routers, and security appliances that run memory-hungry forwarding software
Industrial PCs and edge computing — systems that run for years in unconditioned environments and need connectors that do not degrade quietly
Memory burn-in and test fixtures — sockets that see hundreds of insertion cycles and need the gold thickness to justify it
Repair and replacement channel — aftermarket boards that must match the mechanical behavior of the original design
If your product is designed for a five-year service life, the socket needs to be designed for it too.
If you are comparing DDR4 sockets side by side, here is what actually matters.
Vertical sockets are the default for boards with room above the DIMMs. If your mechanical envelope is tight, look at low-profile options — but be aware that vertical sockets generally give the best thermal airflow over the modules.
White latches (as on this part) are the service-friendly choice: no tools needed, obvious seating confirmation. Tool-style extractors are preferred in high-density layouts where modules sit too close to reach. Match the latch style to how your end customer will actually touch the board.
Through-hole tails win on mechanical strength and are the safer choice for connectors that see repeated insertion force. SMT saves routing space but puts the entire mechanical load on the solder joint. For a part that gets plugged and unplugged, DIP is the conservative, proven call.
Gold thickness is a direct trade-off between cost and contact life. If your product is a consumer board with a short service life, thinner plating saves money. If it is a server, an industrial system, or anything with a multi-year warranty, 30 µ" is the level that keeps contact resistance stable for the life of the product.
Latch and housing colors are not cosmetic. Contrast between latch, housing, and PCB is what lets AOI systems verify seating automatically — which is why this socket pairs a dark housing with a white latch.
Every production lot is traceable to raw-material and plating batches, and sockets are inspected before shipment — not sampled after the fact. You get the documentation you need to audit the part into your own quality system.
This is a mature, running product, not a development sample. That means production lead times you can actually plan around, and stock programs available for repeat orders.
The no-logo version of this socket exists for a reason: some customers prefer a clean, unbranded part for their own housings or regional compliance needs. The same flexibility applies to latch color, plating thickness, and packaging — if your volume justifies it, we will build it your way.
We keep the recommended PCB footprint and routing constraints documented, because a socket that fights the layout is a socket that fails in production. If your layout team has questions, the answer is one call away.
Yes. It is a 288-pin, standard-layout DDR4 socket with the correct keying for DDR4 UDIMM and RDIMM modules. It is not compatible with DDR3 (240-pin) — the pin count and key notch are different, by design.
The heavy plating is sized for repeated servicing — far beyond the few cycles a typical motherboard sees in its lifetime. In test-and-burn-in applications, where sockets see hundreds of cycles, this is the difference between a socket that lasts and one that needs replacing.
The 2.5 mm DIP pitch is the standard through-hole spacing for DDR4 vertical sockets, chosen for its balance of drill size, routing clearance, and joint strength. It is the pitch most PCB fabricators are already set up to handle.
No. The electrical and mechanical specification is identical; only the cosmetic marking differs. The no-logo option exists for customers who need unbranded parts for their own product identity.
MOQ depends on part configuration. Contact CONSHARE with your target volume and we will quote accordingly — including sample quantities for qualification testing before you commit.
Yes. Footprint and layout recommendations are available on request, so your layout team can start routing while the parts are still in transit.
