Signal Loss Caused by IC WTR and IC PA. Often this 'no service' problem is found on iPhone devices and makes users, maybe including you, feel annoyed and confused because they don't know what causes your iPhone no service or always searching Signal. This certainly makes you nervous, because maybe you're waiting for a chat reply from your crush.
First, your SIM card may be damaged. To get started, first check if there is any damage or defect on the SIM card.
Second, the provider's signal coverage is weak. Make sure the provider you are using has strong signal coverage around the area where you live. If it turns out that the signal from the provider in your area is quite weak, then it could be the cause why your iPhone has no service.
Third, there is damage to the hardware or an error in the iPhone software. Damage to this hardware is like damage to IC PA (Power Ampli) or IC WTR (Wireless Technology Research) on your iPhone.
What is a PA (Power Ampli) IC?
As the final signal amplifier. This PA IC is in charge of strengthening the data sending signal so that the cellphone can connect to the operator. When making a call this PA IC will emit a signal through the nearest tower until it can finally be received by the interlocutor.
PA IC malfunction
If the PA IC is damaged, the following problems will arise:
- No signal
- Outgoing signal then lost
- Signal exists but cannot transmit
- Overheating
- Battery drain
What is IC WTR (Wireless Technology Research)?
This IC is a microchips that functions to process or process signals. There are so many tasks from this IC because in it there are many parts such as IF, Oscillator, Mixer, Detector, Encoder, Decoder, and many more, so that this WTR IC can process signals, mix, change frequencies, and many other tasks. The point is that the WTR IC is the center of the controller and controller of the RX and TX signals.Â
WTR IC malfunction
If this IC is damaged, the phone will experience problems such as:Â
- There is no network.
- Looking for a network.
- Exit one of the networks.
- Restart.
- It can even be completely dead.
Causes of Damage to PA ICs and WTR ICs
- Often in areas that are difficult to signal. Causing the machine (IC) to work harder, what will arise is that the temperature on the IC heats up quickly.Â
The solution is if you are in a place with a difficult signal, plain mode is recommended. Because this problem often occurs on any type of iPhone.
   2. Human error, which commonly occurs such as:
- Exposure to water, the effects of exposure to water can result in corrosion and shorting of the engine.
- Falling, may result in damage such as cracking of the IC and damage to other components.
3. Old age of the IC.
   4. Presence of foreign matter such as dust or dirt, and mold.
How long does it take to make IC WTR AND IC PA?
The easiest checking sequence is *#06# if the imei comes out then there is damage to the signal. Then on the other hand, if *#06# imei does not appear, it is certain that there is damage to the Baseband IC.
The IC structure itself has very complex components both on the surface and internally.Â
Each part of the IC has a structure that consists of many layers and sticks together with other parts. In each particular part there is also silicon embedded and the rest is stuck on top of it.
With a very complex structure, for the work that our technicians usually do, for example, a light case takes five to fifteen minutes.Â
For heavy cases, the maximum time is up to 3 days. This process takes a lot of time because the components on the iPhone are very small.Â
