Laptop motherboard Services

To brief about the motherboard related problems , as and when the laptop doesn’t function properly and diagnosed by the technician , as it is a board problemthere are 2 choices which has been left to the User to decide upon.

• To replace the motherboard entirely !!
• To rework the defective part alone of the motherboard.

We emphasize a point that, the rework is less expensive than the replacement of the motherboard itself .On the other hand it doesn’t require to replace the motherboard as and when the technican says , there is a board problem.

Symptoms of motherboard problems

There are several symptoms which indicates the motherboard related problem as follows

• No display
• Not powering on
• Intermitent booting
• Intermitent powering on
• Hanging
• Distortion
• Doesn’t deduct the support devices
• Sytem dead .
• Not booting
• Automatic shutdown
• Dull display
• Over heating etc,

For your information, one of the above mentioned symptom may be an indication of the failed BGA component. Generally the technician informs the User, that it is the motherboard problem entirely, and they suggest for the board replacement .The fact is that the technician may or may not have the facility or experience to test the BGA components .In most cases the truth Is other way around. Not necessarily we need to replace the motherboard all the times, and it can be reworked.

Suggestions

When the user, approaches the laptop manufacturer for the motherboard related problems, they would suggest for a replacement of motherboard exclusively .Though the rework is a certain possibility in many cases ,the manufacturer doesn’t support, due to their own policies. But we are here to emphasize that the motherboards are always reworkable as long as it is not damaged extensively.

Technical Info

We are here to remind you, some of the basic information of the laptop motherboard Components as follows, In this motherboard 2 different Packages being used Are

1.SMD ( Surface Mount device) packages and,

2. BGA ( Ball grid array ) packages

As far as motherboard failure is concerned, when it fails it may not respond entirely or it may work intermittently due to any of these IC’s (SMD or BGA ) fail to respond at times. Though the SMD IC’s are quiet possible to rework without much of difficulties, and doesn’t demand a sophisticated hi-tech tools for the rework process. This can be done even with the help of a smaller solder units with the hands on practice. In case of BGA package rework , which require a specific environment, with the hi-tech BGA rework station, support tools, professional practices, technique, analytical tools, and requires a huge spare inventory.

The BGA package identity

The BGA is used in the computer motherboards in the following areas, North Bridge, South Bridge, VGA ,Network , Bios ,Integrated Packages and so on.To specify the form of BGA IC’s as follows:

1.Earlier versions are Leaded IC’s

2.Later versions lead (Pb) free IC’s, called RoHS ( Restriction of Hazardous Substances ) compliance.

BGA usage and Issues

BGA ( Ball Grid Array ) utility, which is predominantly used these days in the hi-tech electronic industry, for example, laptops, mobile phones, desktops, etc. is a sensitive package ,which can get damaged due to wear and tear issues, or voltage fluctuations, or due to handling mistakes too.

BGA rework required environment

The BGA packages are sensitive, to static energy like other semi conductors .It requires a proper anti-static environment to handle such. Even a slightest variation of static energy can spoil the components so easily. The packages has to be handled in a proper way right from receipt through storage, testing, assembling and transportation.

The technical Challenge

Since the manufacturers keeps developing the BGA packages for laptop motherboards with innovations all the time, due to the growing demand and technical requirement of the users,the BGA rework company has to be on toes all the time to face the quick changes, of the industry and respond accordingly.

Cost effective solution

We recommend BGA reworks predominantly , the reasons are it is cost effective as compared to the motherboard replacement and not only that it becomes reliable when the defective BGA package gets reworked, the motherboard rejuvenates and it becomes functional again.

Dependability

We ANR Electronics, with our experience in terms of BGA reworks are concerned, It is reliable, trusted and we can assure you the long term utility of your products .
