A worn or mismatched nozzle quietly decides your yield

Nobody orders a mounter because of its nozzles — but the nozzle is the only thing that actually touches your component. Its tip geometry sets whether a 0402 lifts square or skews; its bore and vacuum path set whether a part sticks or drops; its material sets how fast it wears. On a high-mix EMS line, the nozzle is where pick errors, tombstoning and 'mystery' reject spikes really come from. Southern Machinery makes the nozzle the predictable part.

• The tip sets the pick. A mounter does not pick a component; it picks a position through a tip. When the tip is wrong for the part — too wide, too narrow, the wrong material — the head reaches, misses the centre of gravity, and the placement is marginal. Every mispick traces back to a tip that was never matched to the part.
• Wear is silent until it is a reject. Ceramic and metal tips drift by microns as they wear; rubber tips harden and lose grip. Nothing alarms when this happens — the reject rate simply climbs and the operator blames the feeder, the tape, the program. By the time it is noticed, dozens of boards have been reworked or scrapped.
• OEM pricing squeezes the spares budget. Genuine nozzles are expensive and often carry long lead times, so factories run them past their useful life to avoid a stop. That is a false economy: one stopped head costs more in an hour than a whole set of matched nozzles. A traceable aftermarket source turns the spares line from a hostage into a plan.

From your head to a fitted nozzle in six documented moves

Nozzle supply is not catalogue roulette. It is a matching discipline: read the machine, cross-reference the part number, choose the geometry and material for the actual component, then verify dimensions before it ever reaches your line. This is the sequence Southern Machinery engineers follow on every Yamaha order, and it is the same one we invite you to run against your own part master.

• Read the mounter and head. Everything starts with the machine model and head — YS12, YS24, YSM, YG100, YG200, YG300, YV88, YV100, YV112, YT16 or MG. The head fixes the shank, the holder interface and the vacuum take-off, so it is the first fact we record.
• Cross-reference the part number. We match your nozzle against the Yamaha Mounter Nozzle List and the supplier document — the KM0, KV6, KV7, KV8, KGS, KGT, KGR, KHN, KHY, KLF and LC/LG dispenser series — so the replacement carries the same identity your program expects.
• Choose the tip geometry. The component decides the tip: a 0402 needs a fine single-bore tip, a QFP or large electrolytic needs a wide or multi-bore gripper, an odd-form part may need a V-shape, narrow-pitch, reflector or Y-shape (王) profile. The bore is stated as inner/outer diameter — Φ0.4/Φ0.7 up to Φ6.0/Φ4.5.
• Select material and coating. Ceramic for fine-pitch, low-static, long-life picking; tungsten or spring steel for rugged larger parts; rubber or silicone for sensitive bodies; metal with O-ring where a mechanical gripper must close on a lead or terminal. Material is a wear-and-grip decision, not a default.
• Manufacture and dimensionally verify. Each nozzle is ground to the OEM dimensions and checked — tip diameter, bore, concentricity, shank fit — before it ships. The document records single/double action (1D/1S, 2D/2S) and pitch values (P=0.8 to 2.0 mm); those are the numbers we hold to.
• Drop in and confirm the first pick. Because the fit is dimensional to the head holder, the nozzle drops in without re-tramming. We ask for a first-article pick on your own tape so the match is proven on your line, not just on the drawing.

Which Yamaha head, which nozzle series

The table below maps the mounter families in the Southern Machinery document to the nozzle P/N series and the component sizes they cover. Use it to find your row, then send us the exact part number for a dimensional match.

Configure the nozzle to your part, not the other way round

Once the series is matched, these are the choices that turn a generic tip into the right tip for your component and your wear pattern.

• Tip material selection. Ceramic, tungsten, spring steel, rubber or metal + O-ring — chosen for the part body, the pick force and the wear life you need.
• Bore & action. Single or double bore (1D/1S, 2D/2S) and pitch P = 0.8 – 2.0 mm, matched to lead spacing and vacuum capacity.
• Special geometries. V-shape, narrow-pitch, reflector and Y-shape (王) profiles for fine-pitch ICs and awkward odd-form parts.
• Spares kits & batch. Named-part-number kits with the right mix of tips on the shelf, so a swap is a morning's work, not a wait.
• Nozzle cleaning program. Pair the nozzles with an S-6200 / SCM24 automatic nozzle cleaner to recover suction and extend tip life between swaps.
• Custom design from a photo. No catalog tip fits? The documented 5-day design service returns a bespoke nozzle concept from three photographs — no drawing required.

How to order a nozzle that fits first time

Getting a matched nozzle is a short, repeatable process. Here is the sequence we run with every new EMS customer, so the part arrives ready to drop into the head.

• Identify the machine and head. Note the mounter model (YS/YSM/YG/YV/YT/MG) and the head position. A photo of the head and the existing nozzle is enough to start.
• Give us the part number. Send the OEM nozzle P/N (KM0 / KV6 / KV7 / KV8 / KGS / KGT / KHN / KHY / KLF / LC / LG series) printed on the nozzle or in your spares list.
• Confirm geometry & material. We check the tip size, bore and material against the component you place, and flag anything that should change for your wear pattern.
• Sample & dimensional verify. For new or custom tips we ship a sample and confirm tip diameter, bore, concentricity and shank fit against the drawing.
• Fit to the head. Drop-in fit to the OEM holder — no re-tramming. Run a first-article pick on your own tape to confirm the match.
• Maintain & schedule swaps. Track cycle counts, clean the vacuum channel, and reorder from a named part number before the tip drifts into a reject.
