juottolaitteet

Juottolaitteet (soldering equipment) are tools and devices that provide controlled heat to join metal components with solder. They are central to electronics assembly and repair, and are also used in jewelry making and some plumbing tasks. The core function is to heat solder enough to create a metallurgical bond between surfaces.

Key components include:

- Soldering iron or pencil (juotoskolvi) – a heated tip that melts solder. Tips vary in shape (conical, chisel) and many models offer adjustable temperatures.

- Soldering station (juotosasema) – a standalone unit with temperature control, often digital, that powers a separate iron.

- Hot air rework station – uses a directed airstream and adjustable temperature to reflow or remove surface-mount components without direct contact.

- Desoldering tools – devices to remove solder, such as suction pumps and desoldering braid.

Materials and consumables:

- Solders (tin-lead or lead-free) and flux (juotostahna) improve wetting and flow. Lead-free alloys are common for RoHS compliance.

Accessories and safety:

- Flux, wick, tweezers, third-hand aids, magnification, and suitable fume extraction.

- Safety considerations include adequate ventilation, fume extraction, ESD protection, and eye protection. Proper temperature control helps prevent damage to components and boards.

Maintenance:

- Keep tips tinned, clean with a brass sponge or proper cleaning pad, and replace worn tips. Regular calibration of stations ensures stable heat delivery.

Applications and standards:

- Widely used in electronics manufacturing, prototyping, and repair. Compliance with RoHS and related standards influences material choices and process parameters.
