PAIN-0101

Skew between differential pairs

P/N legs of a MIPI lane built with 2 mm length mismatch — eye diagram collapses at 1.5 Gbps, host MIPI receiver retrains constantly.

PAIN-0202

FPC contacts on wrong side

ZIF connector expects gold pads facing down, FPC delivered with pads up — link does not negotiate at integration, customer chases firmware for two weeks.

PAIN-0303

Bend-radius violation at exit

FPC routed with a 1 mm fold at the connector exit; copper trace fractures after 200 thermal cycles, signal drops intermittently.

PAIN-0404

Wrong cable for eDP / GMSL impedance

Standard 28 AWG twisted pair substituted for 100 Ω matched eDP cable; impedance comes back at 85 Ω, eye fails at the panel.

Customer names redacted; specifications, volumes, and outcomes are preserved as delivered.

Imaging OEM·Europe·Representative program

An imaging OEM experienced a critical production halt due to high impedance defects in a micro-coaxial cable assembly used for a beta production series.

Challenge: A significant share of an AWG #40 micro-coax 1:1 assembly lot failed due to high impedance, leading to order cancellation, a demand for refunds, and a major trust deficit.
Solution: Halted production immediately and conducted joint technical analysis with the customer's engineering team to identify the root cause — a specification definition and testing-method mismatch between the customer's RF lab and our incoming impedance verification. Updated test specifications, provided new test reports, manufactured replacement samples, and processed a full replacement order.
Result: Successfully resolved the quality complaint, secured a full replacement order for the defective lot, and maintained the long-term partnership. The corrected impedance verification procedure has been applied to every micro-coax assembly since.

Display and high-speed signal cable failures are almost never about workmanship — they are about three numbers most shops do not measure: differential impedance, intra-pair skew, and the dielectric constant of the cable jacket. A FFC that passes continuity perfectly can still drop a 6 Gbps GMSL link because the impedance came back at 85 Ω instead of 100 Ω. We TDR every new BOM line and capture an eye diagram before the lot moves, because the moment you ship without that you have lost the diagnostic path for any field failure.

FAQ · SPEC_QUERIES

Procurement questions.

Do you build to controlled impedance targets like 100 Ω eDP or 75 Ω GMSL?+

Yes. Every new BOM line is TDR-swept on a Tektronix DSA8300 with the impedance trace attached to the first-article report. We hold ±10% on 100 Ω differential and ±5% on 75 Ω HSD. Cables outside spec are quarantined before shipment, not patched at QA.

Can you length-match differential pairs to a tight skew spec?+

Yes — standard ≤ 0.5 mm pair skew at the connector with a length-match fixture in line. Tighter tolerance (≤ 0.25 mm) available on request for 10+ Gbps applications. Skew is verified per lane on multi-lane MIPI and GMSL builds, not just on a single representative pair.

Will you build I-PEX CABLINE-CA II or VS micro-coax assemblies?+

Yes — both. I-PEX CABLINE-CA II and CABLINE-VS are core stocked families in our micro-coax library, with AWG #36 through #44 stock and inspection under 30× microscope. We have built CABLINE-VS programs for thermal imaging and machine-vision customers; the impedance-verification procedure is documented and the test report ships with every lot.

What is the bend-radius rule on FPC at the connector exit?+

Minimum static bend radius per vendor datasheet, with a stiffener reinforcement applied at the connector exit by default — we do not assume the customer specified it. Dynamic-flex FPC (cyclic motion) is qualified on our flex rig before lot release. We flag bend-radius violations at DFM, not at field failure.

Can you do an eye diagram capture on production lots?+

Yes. Eye diagram on first article is standard for any controlled-impedance build. 100% eye capture available on a per-unit basis for critical medical or automotive ADAS lots — priced as a dedicated test station, typically adds 8-12% to unit cost. We recommend it on GMSL2 and MIPI lanes above 3 Gbps.
