Placement head and gantry maintenance

In brief. Scheduled maintenance of SIPLACE TwinHead and CPP heads, every version of the CP20, and the gantries. Two levels: the short service every 3 months, on the head only, and the full service every 6 months, on head and machine; CP20 and TwinHead have their own rules. Downtime ranges from about 2 hours to 4–5 hours per head, agreed in advance.

On ASMPT/SIPLACE lines since 2021 Downtime agreed in advance Across Italy

Two maintenance levels

A placement head works by suction: along with the components it draws in dust, which over time clogs the air channels until a segment stops working. Regular maintenance prevents this.

3 months

Short service

Head only: disc filters replaced; DP and Z axes of the head lubricated; ultrasonic cleaning of the air distributor only; O-rings and seals checked and replaced only if worn, except the PRV valve O-rings, which are always replaced. No work on the machine.

Animated diagram: replacing a segment's disc filterThe dirty disc filter slides out of the segment's housing, a new one slides into its place, and then air flows freely through the channel.
6 months

Full service

On the head: disc filters replaced; DP and Z axes lubricated; DP axis tubes replaced; all O-rings and seals replaced with new parts. On the machine: X and Y axes lubricated, oilers and air filter replaced.

Animated diagram: full maintenance of the segment, with disc filter and thin tubeThe worn disc filter slides out of its housing and a new one takes its place; then the old thin tube beside the segment is pulled out and replaced, and finally a flow of air runs through the channel and the tube.

The PRV valve drives the segment's venturi at the pick-up and placement point (segment 1, position 0 of the star axis). It fails often, so we recommend keeping two spares.

Head by head, with the expected downtime: CP20, CPP and TwinHead.

CP20 head maintenance (C&P20, CP20A, CP20P, CP20P2)

We work on every version of the CP20, the 20-segment head: C&P20, CP20A, CP20P and CP20P2. It is the most delicate of the three: the coupling between the axes and the star needs care.

3 months

Full, without the tubes

Every 3 months, full maintenance of the head, except the DP axis tubes.

6 months

Tubes and machine as well

Every 6 months, the DP axis tubes are replaced as well and the machine is serviced.

CP20

20 segments

Animated diagram: maintenance of the 20-segment head, every 3 months and every 6 monthsIn the first round the 20 segments of the star head light up one after another, while the DP axis tube beside it stays the worn one. In the second round, marked by a second dot lighting up, the segments light up again, the old tube comes out and the new one goes in, and the machine axis under the head lights up for a moment.

Expected downtime: 4–5 hours per CP20 head.

CPP head maintenance

The CPP, the 12-segment head, follows the two levels: the short service every 3 months and the full service every 6 months.

3 months

Short service

About 2 hours of downtime per CPP head.

6 months

Full service

About 3 hours of downtime per CPP head.

TwinHead maintenance

The TwinHead has no separate levels: the service is always the same, every 6 months.

6 months

Always the same service

About 2 hours of downtime per TwinHead.

The gantries

On the gantries that move the heads: bearings greased, rails oiled with the lubricant specified by the manufacturer, fans cleaned and dust removed, vacuuming, vacuum pump filter and air filter.

Each gantry carries one head. Machine downtime is the total of the times for the heads fitted, and we agree it with you before the visit. For the machines as a whole, SIPLACE SX, X and TX, there is machine maintenance.

Technical data sheets and head specifications: on the official ASMPT website.

Advance notice

To plan maintenance we need at least one month's notice for a single job and 2–3 months for periodic maintenance. Scheduled maintenance is also included in the Ongoing support formula, on a contract or as planned visits; spare parts are not included.

If a head has already stopped, don't wait for the next service: write to us straight away and we start from head and gantry fault finding, remotely.

// Frequently asked questions

Questions about head maintenance

How often should a SIPLACE head be serviced?
It depends on the head. On the CPP, the short service every 3 months and the full service every 6. On the CP20, in every version, full head maintenance every 3 months without the DP axis tubes, and every 6 months the tubes and the machine as well. On the TwinHead every 6 months, always with the same service.
What is the difference between the short and the full service?
The short service covers the head only: new disc filters, DP and Z axes lubricated, ultrasonic cleaning of the air distributor, O-rings and seals changed only if worn, except those of the PRV valve, which are always new. The full service also replaces the DP axis tubes and all O-rings and seals, and on the machine it lubricates the X and Y axes and changes the oilers and the air filter.
How long does the machine stop for?
Downtime is the total of the times for the heads fitted: about 2 hours for a TwinHead; for a CPP about 2 hours for the short service and about 3 for the full one; 4–5 hours for a CP20. We agree it with you in advance.
Which CP20 versions do you work on?
All of them: C&P20, CP20A, CP20P and CP20P2.
What about DLM heads?
They are not part of scheduled maintenance today: DLM3 and later heads need specific jigs that we do not have. Write to us and we will assess it case by case.
Why keep spare PRV valves?
The PRV valve drives the segment's venturi at the pick-up and placement point, and it fails often: that is why we recommend keeping two spares. Its O-rings are always replaced during maintenance.
How far ahead should maintenance be booked?
At least one month for a single job, 2–3 months for periodic maintenance. For a fault, though, write to us straight away: there is our head and gantry fault finding.
Can maintenance be covered by a contract?
Yes: it is also included in the Ongoing support formula, on a contract or as planned visits. Spare parts are not included.
