How to Choose Best Cell Phone Repair Rework Station

If you are a cell phone repairman, you must be familiar with phone repair rework station, or you can also call it hot air station, it is generally used for soldering and desoldering motherboard BGA IC chips. There are all sorts of good SMD rework stations from market like WL, Quick, Baku, Atten and so on. It is an essential tool when it comes to reworking a cell phone motherboard. The term rework just means you are refinishing or repairing an already reflowed board, and it is a term commonly used in the electronics world. 





There are two control knobs with any SMD Rework Station. One control knob is to control flow of Hot Air while the other control knob is used to control temperature. Hot air flow through nozzle attached to the handle. This hot air helps to melt solder paste beneath the IC. An SMD Rework Station is also used as BGA Rework Station using some additional equipment and set-up such as an iPhone PCB Holder , Stand for the Rework Station and a Pre-heater to give heat from the bottom.

Some common cell phone rework examples:

Tombstone parts. This is when a part (usually a resistor or capacitor) reflows only on one side. The part usually sticks strait up resembling a tombstone.

Cold joints. This is similar to a tombstone except the parts might not be sticking strait up, making it harder to see the connection that is not being made.

Polarized parts that have been placed incorrectly (backwards, shifted x degrees off). These include ICs, diodes, some capacitors, connectors, etc.

Removing defective parts. Sometimes, during the IC manufacturing process, errors can arise and go unnoticed. These ICs are then placed on perfectly good PCBs. Hot-air is great for replacing these bad parts.

Missing components. The smaller the component, the easier it is for it to disappear. This can happen before or during reflow, resulting in a spot where something should be, but isn't. Hot-airing a new part in its place is a snap with this rework station.

Solder  jumper wire. If too much solder or solder paste is used, the result can be jumpers on one or more of your IC's legs. Hot-air can sometimes be used in conjunction with a flux pen to remove these pesky buggers.

Rework isn't the only thing a hot-air rework station is good for. Other uses include:

- Shrinking heat-shrink onto wires.

- Salvaging electronic components from old PCBs.

- With the correct settings, hot-air can be used to heat up and bend certain plastics.

- They can also be used to heat up hot glue to remove or reposition items that were glued incorrectly.



How to Use SMD Rework Station

Plug in the power cord of the station and switch ON.

Now switch ON the Power Switch of the Station.

Adjust the Temperature and Air Pressure. Temperature and Air Pressure or Air Flow must be balanced properly for proper soldering and desoldering. Too much heat and less air flow will produce too much heat that can damage the PCB of the Mobile Phone. Similarly less heat and too much air pressure will lead to improper desoldering and soldering.

Most SMD Rework Stations have automatic power cut feature. This means that when the handle is placed on the holder power gets off.

When repairing is done, switch OFF the station. The station will now automatically blow cool air so that the heater inside the handle gets cool and do not cause any damage.

Tip: When soldering or desoldering using a SMD Hot Air Rework Station, always try to preheat the PCB by giving heat from some height and then gradually bring down the handle of the station. If you give sudden heat to the component of the PCB then other components and the PCB itself can get damaged due to thermal chock. 

How to Choose the Best Rework Station

While there are many SMD Rework Stations available in the market. Some are of best quality but are expensive. Others such as Chinese SMD Rework Station are economical / cheap but they do not give satisfactory performance. Branded Rework Stations are repairable and parts are easily available. Always buy ESD-Safe SMD Rework Station to avoid any damage due to Static Electricity. Some of the best brands for SMD Rework Station are Quick, Wl, etc.
