We start our first topic with this Example:

when we are checking a wire and we want to check whether the wire is broken or not form inside in the phone PCB we use beep testing. 

continuity test with multimeter

when we connect the battery to phone PCB continuity is present when two points in an electrical pathway have a connection this connection must be continuous without any break or open

1. One is called Primary line
2. Two is called secondary line

Multimeter Continuity Mode for Jumper Mobile

in phone PCB checking with multimeter continuity mode is extremely beneficial in verifying primary and secondary line breaks using a multimeter

Continuity test with multimeter example:

I can check to see if connections are linked together with a continuity test function. this is represented by a sound wave symbol on the measurement scale of the multimeter

Mobile Jumper Solution on Mobile Battery Connector

in every mobile PCB, there is a battery connector. if you know it you know a mobile jumper solution. it has three tips one is called primary line VBAT battery voltage positive. 2nd is called secondary line ground or GND means negative and 3rd is called Battery Status Indicator or BSI. in Phone PCB ground is the baseline

Ground Continuity Test with Multimeter 

mobile repairing students know in mobile repairing course hardware Ground Continuity Test with Multimeter is the first lesson on the Mobile Jumper topic. As we know power comes with a VBAT, GND, and BSI line in mobile PCB with mobile battery, Secondary Ground Line on mobile PCB is signified by the yellow strip that you see all across the phone PCB. first of all, we will check the Ground Line in Phone PCB. to check it is connected to battery connector set your digital multimeter on continuity buzzer.

then place one probe on connector GND and touch another probe on that yellow strip if you hear a beep sound its means it is minus. 

PCB Grounding Techniques

do you have a question how to check mobile components are connected to grounding line in phone PCB grounding techniques? this updated information helps you. to check which print is ground apply the same technique we use this method to check whether two points are connected or not to check which component leg is connected to ground apply the same method. if you hear buzzer sound and its show 0 reading its means it is minus.

Mobile components

you can also use this technique To check primary line VBAT. what is vbat in mobile? To answer this question, vbat stands for "voltage battery," The vbat voltage mobile that is supplied to a phone battery is maintained between 3.6 V to 4.2 V which makes sure that the phone battery does not overheat or get damaged. vbat in mobile means voltage battery active. watch the mobile phone repairing course video lesson below to do the practice this whole process by your own self.

Read and download the latest information on the mobile jumper solution here. jumper setting is typically best when you need to connect two different points on a cellphone there could be internal disturbances in the circuit of the handset which are connecting these two points and because of the internal disturbance or a breakage in the circuit, the father or data may not be traveling from one point to the other easily and in those cases, we use jumper setting to try and connect those two points directly thereby ensuring the correct transmission of power, data, and piles voltage from one end to the other end but in order to determine whether you need to do jumper setting.

Tracing & Testing VCC main and GND points of a iPhone PCB

iphone 6 battery connector

now in this iPhone, the first aspect that we were going to be checking is the connectivity between the battery connector and two other important basic electronic components that transmit power to the rest of the circuit of the cellphone now in order to test out the connectivity in the phone PCB you need to use the multimeter!

and you can hear the beep and once you hear the beep the multimeter is perfectly alright let's go ahead and test the connectivity on the board now typically we are going to be starting off with checking the battery connector

Step 1 Check Shorting on Phone Battery Connector

positive negative BSI 

Battery Connector connects the battery positive and negative to the mobile PCB internal plus and minus copper wire prints. if you don't know how to check Shortage on phone circuit from the battery connector read this article how to fix a short circuit iPhone

Step 2 Checking Phone PCB Ground Resistance with Multimeter

you need to identify the positive and the negative points on a battery and we already know that the negative point on the battery is what is the background connection as you see the yellow color line is the GND line of the battery that is traveling all through the mobile PCB so let's keep the probes on one end and connected and now we can hear the beep this basically means that the battery connector negative point is here. if two GND points are connected you will hear the beep sound if not you will not be able to hear a beep sound in these points by segmenting the entire negative line into smaller parts you will be able to exactly trace where the breakages in the entire negative line once the breakage is identified you will then need to use the jumper setting option and try and ensure that the wire is or the circuit is reconnected and is properly functioning

Positive Line VBB or VCC Main in iPhone PCB

now this is how we check the negative line now let's move on to the next part which is a positive line now a positive line cannot be very clearly seen like the negative line the positive line is typically connected to very specific components or ICS and supplies power to each of those components so it's not very easy to identify and it's not open unlike the negative line hence you need to ensure that you are able to trace the positive line effectively after reading through the circuit diagram of the respective iPhone PCB

+VBAT(battery voltage) on Phone PCBs

now one of the common things that we can do to check the positive ways is to touch the positive terminal +VBAT of the battery connector to this layup capacitor now this component is a very common component that you will find in most phone PCBs and this is a commonplace where the positive ways is usually connected you may be able to identify that in different phone PCBs

Read cell phone circuit board components to learn Identification of Mobile Phone Components The following blog post has information about their functions and purpose

once you identify and able to detect that you will be able to touch the positive direct ways in the PCB the positive connector of the battery a connecting point to the specific nonpolar capacitors, resistance and other components and you can check whether the direct positive ways is intact or not that if there is a breakage here you may not be able to connect or connect the jumper wire from the battery connector VBAT

Step 3 Checking Primary line VBAT battery voltage positive

use the back end of the phone battery connector as you can see here in the pictures

black probe multimeter is connected to vbat

there's a small point at the back of the battery connector which is connected to the front of the battery connector so you place one end of the meter prob tip on the backside of the battery connector point and the other on the other connecting point in the PCB and check whether you are able to get a beep sound nowhere you will be able to connect the jumper clearly without any issues like I just said before in the article the back point is connected to the power point you can hear the beep and from here you can connect the jumper wire to the next point for you to be able to take the positive ways ahead but you need to ensure that you read the phone circuit diagram clearly before you attempt any of this

What Do You Do When a Smartphone Won't Turn On?

in a smartphone, this is a common issue. to fix this in smartphone try to long press the Power Button. in many cases, the power button won’t work because the phone is basically frozen or Historically, the solution is to remove the battery, wait for 10 seconds, then reinsert the phone battery and press the power button again. This removes all the power internally form the smartphone circuit. first, try this to fix the problem. just hold down the power button for ten seconds. If this method doesn’t work, try to press the power button for a bit longer. ten seconds should be suitable for most smartphones, Many smartphones have a method to restart usually by holding down specific keys or buttons on the phone. Much like the Sony Experia and Motorola battery pull where you hold the volume down key and power key simultaneously while the mobile is powered off. Try using a laptop or car charger instead can put a quick charge on phone battery and get it to respond as well. If you have tried these methods and the phone isn’t responsive due to its battery drained 100% Try charging it using a battery booster(12 volts DC adopter with Ampare) this device is used to boost mobile phone batteries if you don't know how to use this device to fix the dead phone batteries read digital multimeter step by step guide article DC Current Measuring topic.
