Hersteller von Siemens-SMT-Pipetten für die smarte EMS-Leiterplattenbestückung

A nozzle is 15 grams of plastic, ceramic or rubber - and it carries your whole placement yield

Feeders, programs and operators all get attention. The tip that actually touches every component usually gets cleaned late and replaced later. These are the three failure patterns we are asked to fix most often on SIPLACE-style lines.

• Mis-picks and skewed placements trace back to the tip. A worn bore, a chipped ceramic edge or a hardened rubber lip changes the vacuum column and the contact geometry. The first symptoms are small: an occasional miss, a rotated 0603, a rework that nobody blames on the nozzle. By the time the line flags it, hours of CPH are gone. The maintenance manual is blunt about the mechanism - dirt and wear are removed with a brush and compressed air, and…
• OEM lead time and price hit a consumable you replace on schedule. Nozzles are listed as wear parts in the X-series manual, alongside filter disks and hoses. Wear parts are a budget line, and a budget line should have a second source. We cross-reference by item number - the 0034xxxx and N610xxxx codes printed in the catalog and in your purchase history - and quote against the same geometry, not a guess.
• Odd-form parts have no catalog answer at all. Transformers, E-caps with sleeves, brackets, connectors with locking clips: the datasheet stops at the standard tip sizes. That is where design and manufacturing starts - a gripper or suction geometry drawn around the component, checked on your head, then documented like a catalog part so the next engineer can reorder it.

How a Siemens nozzle order is actually built

Nine steps, each one leaving a document. The point is not speed alone - it is that every claim on this page can be traced to a datasheet, a manual section or a test you can repeat.

• Component and head survey. You send the component (code, package, photos), the placement head (12-star, C&P20A, CPP, TwinHead) and the symptom. Head type fixes the shank, the collet seat and the changer behaviour before anything else.
• Item-number cross-reference. We match your code against the special-nozzle catalog (0034xxxx, 030xxxxx), the ASM/Siemens tables in our supplier booklet (900 and 1000 series for 12-head and 20-head) and the manual's wear-part list (20xx, 28xx, 7xx, 9xx, 10xx, 12xx, 30xx).
• Material and geometry selection. Vectra liquid-crystal polymer bodies for the special versions, with aluminium, steel, POM, PA6.6 or ceramic tip inserts depending on abrasion and weight. Rubber and PU tips for large or delicate parts - the catalog itself carries restrictions such as 'for rubber tip 12U1, 12U3'.
• Machining and moulding. Standard geometries are produced from the documented dimensions; custom tips are drawn, approved, then cut. Bore, cone angle and seat are the three features that decide whether a nozzle picks like the original.
• Functional test. Vacuum draw-through, bore clearance against the datasheet (a 731 is Ø0.9 mm with a 1.2 mm slot), and runout on a mandrel. The manual's own rule applies to our parts too: no bulk cleaning, no tips knocked against metal.
• First article on your head. A sample runs on your machine, in your program, on your component. Pickup rate and miss records are the acceptance sheet - not a laboratory certificate that never saw a feeder.
• Batch with identification. Production batches carry the item code and the colour-ring convention you already use on the 900-series parts, so the magazine slots load without retraining the operator.
• Kitting to head layout. Nozzles arrive in rack or magazine-ready sets matched to your head layout, with the cartridge-rack and cleaning-box tooling listed in the manual available in the same order.

What we actually supply for Siemens / ASM heads

The families below are named as the supplied documents name them. Where a series label differs between documents, the disclosure table says so.

• 7xx / 9xx special nozzles for the 12-star head. 128 datasheets, edition 12/2004: Vectra bodies with PU, aluminium, steel, POM, PA6.6 or ceramic tips. 108 of them are marked as handled with the nozzle changer; the rest state a restriction - verify against your head and changer firmware before ordering.
• Ceramic and plastic families 10xx / 12xx / 20xx / 28xx / 30xx. The wear-part tables of the SIPLACE X-series manual list these as nozzles and ceramic nozzles per configuration, with dedicated cleaning boxes, cartridge racks and guiding plates. We match by item number and by the head you run them on.
• Custom nozzles, grippers and rubber-tip versions. Chucking fingers, gripper assemblies, large-bore rubber tips (the booklet's Φ8.0 and Φ10.0 rows) and odd-form picks drawn from your sample - designed, manufactured and then documented like a catalog part.

Open questions we disclose instead of smoothing over

Three good documents still disagree across seven years of editions. These are the points a buyer should confirm against their own machine before trusting any supplier - including us.

How many nozzles your head carries - and what that means for spares

The manual names the head families and their nozzle counts. The table converts that into the spare-set arithmetic a planner actually needs.

What to order alongside the nozzles

Six things that turn a nozzle purchase into a working spares programme on a SIPLACE-style line.

• Nozzle cleaner (S-6200 / SCM24). The manual's cleaning tasks - brush, compressed air, ultrasonic with distilled water - are exactly what our automatic nozzle cleaners run on a schedule instead of at midnight. Manual and installation documents are on the catalog board.
• Cartridge racks and cleaning boxes. The manual lists cartridge rack 10xx [03071700-xx], cleaning box for ceramic nozzles [03055736-xx] and guiding plates. We supply compatible storage and bath tooling so tips never rest on metal.
• Rubber and PU tip versions. For large or delicate parts: the booklet's Φ8.0 and Φ10.0 rubber rows and the catalog's 'for rubber tip 12U1, 12U3' restrictions. Tip hardness is chosen against the component, not the machine.
• Colour-ring identification. The 900-series parts in the booklet carry coloured rings. We reproduce your existing colour convention or set a new one at no tooling cost - mis-slotted nozzles are an operator-error killer.
• Custom gripper assemblies. Chucking fingers, E-cap grippers and odd-form jaws - the booklet and our custom album show the families; each one starts from your sample and ends as a documented part number.
• Mixed-brand consolidation. One PO for the ASM/Siemens line and the JUKI, FUJI, Panasonic, Yamaha or Assembleon neighbours. Same matching discipline, one packing list.

The maintenance sequence the manual itself prescribes

Six steps from section 4.7 of the SIPLACE X-series manual, written for nozzles. Follow them and a requalified nozzle behaves like a new one; skip them and no supplier can save the placement yield.

• Prepare safely. ESD protection on (the manual ships an ESD wriststrap with the service box), head parked, hood secured per your machine procedure.
• Set down in the changer. 'Set the nozzles down in the nozzle changer' - manual 4.7.3. Never pull live nozzles out of a running head.
• Brush, no bulk. CAUTION in the manual: do not clean nozzles in bulk. Apply slight pressure and move the brush back and forth to lift partially dissolved dirt.
• Blow through. Compressed air through the bore, then return each nozzle to its magazine slot or cartridge rack - tips hanging free.
• Ultrasonic only for ceramic. Distilled water in the bath; only the ceramic tips enter the fluid by about 2 mm; level within ±2 mm of the prescribed height. Fill and tooling per manual 4.7.4.1.
• Verify before reload. Vacuum check and a short pickup trial on the head. A nozzle still out of spec after cleaning is a replacement, not a second wash.

Identify, verify, replicate - then support

A second source is only useful if the match is provable. This is the sequence every nozzle order runs through.
