What is a reworking station?

Rework stations are also de-soldering stations, and its soldering function allows operators to easily repair metal using metal solder. Hot air generated from the station is also useful for melting solder, making it liquid for short periods of time.

Do I need a hot air station soldering?

Although you can certainly get by with just a soldering iron and desoldering station — as many people have for years — a hot-air rework station may be better for you if you're actually going to use all of its additional features.

Which is the best SMD rework station?

How does reflow work?

During the reflow soldering process, the PCB passes through an oven. This causes the solder paste to melt (reflow). After the oven stage, the circuit board undergoes a cooling stage. At this point, the solder sets, sealing the electrical components to the circuit board.

What temp does solder reflow?

The typical reflow temperature range for Pb-Free (Sn/Ag) solder is 240-250°C with 40-80 seconds over 220°C. It should be noted that the recommended Sn/Pb reflow temperature range are less critical, and that minor deviations in temperature of equipment and components generally do not create soldering problems.

What is SMD station?

Surface Mount Device (SMD) rework station is also known and referred to as hot air blower. They are used for soldering and de-soldering of integrated circuit (IC) parts or chips and Ball Grid Array (BGA). It is also used to repair mobile phones and Printed Circuit Boards (PCB).

Can I use hot air gun for soldering?

Hot air is used for soldering, desoldering and repair work in the hobby workshop as well as for recycling PC and mobile phone components. With a hot air blower, electronic components are easily desoldered from circuit boards and metal parts simply heated and deformed without the use of a soldering iron.

Can you solder with a hot air gun?

As well as all kinds of other DIY jobs, a heat gun is very handy for soldering copper pipes. It's most suitable for working with soft solder with a melting point below 400°C.

Can you reflow solder with a heat gun?

A common heat gun is an inexpensive way to reflow, or reattach, electronic components that have been soldered together. While a regular hot-air solder rework station could cost more than $100, a common heat gun available from most home improvement stores should cost no more than $50.

What temp does solder melt?

Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used.

How hot does a heat gun need to be to melt solder?

The typical lead-free solder has a melting point around 217 degrees C, so you'll have to get the leads and pads up to that temperature before trying to remove the component.

What temperature do you need to Desolder?

Otherwise, surface-mount components must be removed by heating the entire component to a temperature sufficient to melt the solder used, but not high or prolonged enough to damage the component. For most purposes, a temperature not exceeding 260 °C (500 °F) for a time not exceeding 10 seconds is acceptable.

What is BGA machine?

A BGA rework station is a machine that can be used to refinish or repair printed circuit boards (PCBs) with ball grid array (BGA) packaging and surface-mounted devices (SMDs).

How many zones are in reflow?

In the conventional reflow soldering process, there are usually four stages, called "zones", each having a distinct thermal profile: preheat, thermal soak (often shortened to just soak), reflow, and cooling.

How do you reflow a PCB?

The basic idea is to heat the circuit board to a temperature where the solder melts, then let it cool. ... Reflow Soldering

Preheat the oven to ~ 100 degrees Celsius.
Insert board into the oven.
Raise the temperature gradually up to 220 degrees and let it stay there for 1-2 minutes.
Take out board and let it cool.

How many times can you reflow a PCB?

Q: How many times can you reflow a PCB? The general expectation is three times: once for the top side, once for the bottom side, and once for rework. The ultimate limitation comes from the formation of brittle intermetallics between the copper pad and the tin in the solder.

How hot does a reflow oven get?

The reflow oven is kind of like a pizza oven. The board is raised in temperature to about 250°C (~480°F) at which point the paste turns to liquid metal. As the board exits the reflow oven, it quickly cools soldering all the components in place.

How do you reflow a solder joint?

First, add flux to both the bridge and a small area of the solder wick. Then, place the flux-infused area of the wick over the unwanted solder and heat both with the soldering iron. The wick will begin to absorb the solder. Repeat the process until the desired amount of solder has been removed.
