If the YS88 we covered last week is Yamaha's "odd-shape specialist," the YSM20 (Z:LEX series) is the workhorse everybody else fights over. 90,000 CPH, 03015 capability, 140 feeders, and a "one-head-does-both" philosophy — it's the reason YSM20 is still the most liquid used-SMT model in Shenzhen in 2026.
Below is the spec + buyer guide you can drop on your listing page, LinkedIn, or YouTube description.
Yamaha's mid-to-high SMT family splits roughly like this:
| Model | CPH | What it's for |
|---|---|---|
| YS88 | 8,400 | Odd-shape, press-in, long connectors |
| YSM20 | 90,000 (2*HM) | Balanced high-speed + universal, EMS/OEM main line |
| YSM20R | 95,000 | YSM20 "deluxe" — stronger XY, wider scan camera |
| YSM20W | 80,000 | Wide-board version (single lane up to W742) |
The YSM20's pitch is "1-head solution" — one head type covers 03015 chips andL100mm mid-size parts without swapping. That's the differentiator versus Fuji NXT-style multi-module lines, and why EMS houses keep coming back to it .
| Item | Spec |
|---|---|
| Mounting speed | 90,000 CPH (optimum, 2*HM head); ~63,500 CPH (IPC9850) |
| Accuracy | ±0.035mm (±0.025mm), Cpk ≥ 1.0 (3σ) |
| PCB size | Single: L810 * W490 → L50 * W50; Dual-stage: L380 * W490; Dual-lane: L810 * W230 |
| Component range | HM head: 03015 – 45*100mm, H ≤ 15mm; FM head: 03015 – 55*100mm, H ≤ 28mm |
| Feeder capacity | Max 140 types (fixed, 8mm equiv.) + 128 types FES cart + 30 trays (fixed) + 10 (cart) |
| Power | 3-phase AC 200–416V ±10%, 50/60Hz |
| Air | ≥0.45MPa, clean & dry |
| Dimensions / weight | L1,374 * W1,857 * H1,445mm / ~2,050kg |

This is what "1-head solution" actually means on the shop floor:
HM (High-Speed Multi) head — 10 nozzles per head, 03015 → 45*100*15mm. This is the 90k CPH config. One head eats CHIP andmid-size QFP/connector. No head change .
FM (Flexible Multi) head — 5 nozzles per head, 03015 → 55*100*28mm, load-control capable. Slower than HM, but takes tall odd-shapes that HM can't. Often paired HM+FM on a 2-beam machine if the line has heavy异形.
Most "in stock" YSM20s you'll see on the secondary market are 2-beam / 2*HM configs — that's the 90k number everyone quotes. If a listing says FM or mixed, CPH drops, but component envelope goes up. Ask the seller which head set is mounted before you pay.
YSM20R — Yamaha's own "5% faster than YSM20" refresh (2018). 95k CPH champion mode, wider-scan camera (recognizes up to 12*12mm at speed vs 8*8 on base YSM20), stronger XY and ALF/sATS30NS options. If your budget stretches, R is the better long-term hold .
YSM20W — Same CPH logic but single lane stretches to W742 (vs W490 on standard). LED strips, long PSU boards, that kind of thing. Most EMS lines don't need W742, so W tends to sit longer in inventory.
Base YSM20 — Still the "don't think twice" buy. 90k + 03015 + 140 feeders + dual-lane, all for a used price that undercuts a new YSM20R by a wide margin .
New-machine lead time + premium — Yamaha's current-line pricing and delivery don't favor small/mid EMS. A Japan-origin used YSM20 lands drastically cheaper and ships in days, not quarters.
Liquidity = parts peace of mind — HM nozzles, FES carts, sATS/cATS trays — all over Shenzhen/Bao'an. Downtime risk is lower than with niche models.
03015 isn't dead yet — IoT, industrial control, automotive sub-assemblies still run 03015–01005 mixes. YSM20's accuracy bracket (±0.035mm) hasn't aged out.
💡 Rule of thumb for ROI: if your line is doing consumer / IoT / mid-density industrial and you're weighing "new YSM20R vs used YSM20 + a second YS88 for odd-shape tails" — the combo often beats a single flagship on throughput-per-dollar.
HM head nozzles (10 per head * 2 heads) — spring tension + tip wear. 90k CPH lives or dies here.
X/Y dual-beam belts + linear scales — 2-beam 90k config puts more stress on the gantry than 1-beam. Drift shows up as accuracy sliding past ±0.035mm.
FES feeder exchange cart — 128-changeover capacity. A lot of resellers strip this out and sell separately; ask if it's included.
Wide-scan camera + side-view — HM head does 03015 recognition through this. If it's been swapped for a cheaper aftermarket part, small-chip yield drops.
sATS30 / cATS10 trays — 30 + 10 layer count. Missing trays = odd-shape feeding bottleneck even if you have FM head.
The YSM20 is the Yamaha you buy when you want "fast enough, flexible enough, and nobody gets fired for choosing it." 90k CPH, 03015 start, 140 feeders, dual-lane — it's the EMS default for a reason. In 2026, a Japan-maintained in-stock unit is still one of the cleanest ROIs in SMT.
In stock inquiries: tell me your head config (2*HM / HM+FM), feeder count, and whether FES + sATS are included — I can tailor the listing blurb / YouTube script off that exact spec set. Want me to do the YSM20R or YSM10 follow-up next to close the Yamaha series?
