Equipment buying guides

The right equipment starts
with the right questions.

Practical answers to help you compare options and choose equipment that fits your work.

01 / PCB assembly

How to choose a pick & place machine

Start with the boards you build and the production you need.

What should I know before comparing machines?

Prepare your PCB or panel dimensions, component list, smallest and largest packages, and target boards per day. Include expected batch sizes and how often you change products. These details help narrow the choices before comparing prices.

Should I choose the machine with the highest placement speed?

Compare achievable output for your own board. Component mix, feeder arrangement, board handling and job changes affect production time. Ask for a cycle-time estimate using a representative job, especially if you run many small batches.

How do I check whether my components and boards will fit?

Check the supported board dimensions and thickness, component size and height limits, and the vision and nozzle options needed for your parts. For fine-pitch or unusual components, have the supplier review the actual package requirements before ordering.

Why do feeder capacity and feeder types matter?

Your component list determines how many different parts must be loaded. Confirm compatibility with your tape widths, trays or tubes, and check how many feeder positions each setup uses. Ask which feeders are included and which are purchased separately.

What matters most for prototypes and frequent job changes?

Look closely at programming, component setup, feeder changes and first-board verification. A machine that makes these steps straightforward can be a better fit for varied, short runs than one selected on placement speed alone.

What should I send SMTmax for help choosing a model?

Send your bill of materials, board dimensions, placement count and production target, plus details of difficult components. Tell us about your available space and existing assembly process so we can discuss a suitable configuration and any additional equipment.

02 / Dental air supply

How to choose an air compressor

Match the air supply to the equipment operating at the same time.

Do I size a compressor by the number of dental chairs?

Start with the number of simultaneous users, then include other air-powered equipment. Installed chairs alone do not describe peak demand. Share the equipment manufacturers’ air requirements and any planned expansion when asking for a recommendation.

What do airflow and pressure tell me?

Airflow, commonly listed in CFM or liters per minute, describes the volume supplied; pressure is commonly listed in PSI or bar. Compare delivered airflow at your equipment’s required operating pressure, using matching rating conditions. Maximum pressure alone does not tell you whether a compressor can keep up.

Does a larger tank mean more usable capacity?

A tank stores air, but tank size alone does not establish sustained output. Compare compressor delivery, permitted operating cycle and peak demand alongside tank capacity. Avoid choosing only by tank size or motor horsepower.

Do I need an air dryer with an oil-free compressor?

Oil-free and dry air describe different things. An oil-free compressor does not by itself remove moisture. Check the drying and filtration requirements of the equipment you will connect, then confirm whether the selected compressor configuration includes the appropriate dryer.

What should I check about power, space and noise?

Confirm voltage, electrical requirements and available space before ordering. Plan for ventilation, service access and an appropriate location for the operating noise. Use the selected model’s installation instructions when arranging the site.

Can I also run CAD/CAM or other equipment from it?

Include that equipment’s airflow, pressure and air-quality requirements in the sizing review. Some applications call for a dedicated supply. Ask us to review the combined demand rather than assuming a chair-based rating covers every connected device.

What maintenance should I plan for?

Follow the specific model’s schedule for filters, moisture management and other service items. Oil-free does not mean maintenance-free. Ask which consumables your selected compressor and dryer require before purchase.
