No manufacturer wants to experience production line downtime, which is why it’s essential to improve your SMT line productivity with preventative maintenance strategies. Capital Equipment Exchange can not only help you understand the importance of SMT preventive maintenance, but we are also a source for replacement parts on used SMT equipment.

Increase Mean Time Between Failure (MTBF)

It is the goal of every SMT production line we know to avoid equipment failure by any means necessary. Any machine failure on the line is wasting precious time and money. The best way to ensure a higher mean time between failure (MTBF) is to schedule and perform routine preventive maintenance to identify and fix problems before production is affected.

Common Electrical Failures

Electrical failures are common in SMT equipment lines due to heat stress, especially when turning equipment on and off frequently. Being aware of the effects of this simple act is a form of preventative maintenance that can decrease the frequency of many common problems. Many electrical components may experience failure from thermal stress.

  • Power Supplies
  • Resistors
  • Fuses & Coils
  • Transformers
  • Relay Contacts
  • Cables & Plugs

Skipping Preventative Maintenance Is A Bad Idea

During a period of economic downturn, it may be tempting to avoid preventative maintenance downtime to keep production running and income pouring in. However, in our experience, that leads to costly repairs, equipment replacement, and a line that is out of service for a much longer time than any maintenance would have caused.

Common Maintenace Tasks For SMT Equipment

Used SMT pick and place machines are one piece of equipment in the production line that can cause errors on the line if regular maintenance is not performed. They require regular cleaning, especially for nozzles. Poorly maintained nozzles can lead to picking up the wrong components, misplacing components, and even flipped components. All of this leads to eventual board failure.

SMT machine maintenance is essential for every piece of equipment, from screen printers to wave solder machinery and reflow ovens. It’s always worth a small amount of downtime.

  • Inspect & Clean Regularly
  • Clean & Replace Nozzles
  • Service & Repair Exhaust Fans
  • Repair Or Replace Electrical Components
  • Check Cooling Systems & Fans
  • Remove Excess Solder Paste Deposits
  • Replace “Perishable” Parts As Needed

Keep & Update Equipment Maintenance Logs

Creating an SMT maintenance checklist is one way to stay on top of routine and preventative maintenance tasks. We suggest taking things a step further and keeping meticulous service logs for each piece of equipment on your PCB assembly line. If you keep accurate records, you will eventually see patterns and be able to address problems before they happen.

If you know you typically get 1200 hours of production time from your flying probe tester before it needs maintenance, you can plan for that maintenance and keep your manufacturing running smoothly.
