Tricks on how to reball PM ic in iPhone4 in easy way!(TIPS AND TRICKS)

share ko lang po ito para sa inyo,.bali patay po ang unit,una ko ginalaw PM ic,nag ok na kasu hindi nag charge,pinalitan ko UI sa charging usb dock wala parin,.kaya reball ko nlang PM IC.

mas maganda ito kasi minsan kung PM ic ang ipatong mo sa nokia baord may posible pa na masira,kasi initin mo talaga ang PM ic,.ito safe para di agad masira PM ic,.

see pics,.

ayan flat pa mga balls kakalinis ko lang,





ito na,.may mga sirang board kayu like nokia n95,n79,n78,6300 etc,kunin nyo ang signal RF IC nya,.follow lng po sa pic kung panu mag Cut using blade cutter,





ayan guhitan at putulin nang blade cutter bali ang nokia RF IC is 12x12 balls
tapos ang PM ic 11x11 balls,kaya putulin nyo,.see pics.





ayan na putol kuna,.ito na mukha nang ic na nokia,





kaya lagay kuna gamit hotair din kunting alog,.





tapos tanggalin na,.check nyo pics may mga paa na,.ayus,.pwede na kabitan nang PM ic,





ayan kabit kuna,.





check kuna unit,.salamat at may resulta naman,.





ito lang po para sa mga nahirapan lang mag reball,.kasi ang bagong PM ic may mga paa nman,.sa mga walang paa lng na PM ic.

tablet battery(convert nokia battery to tablet battery)procedure inside.

mga sir share ko lang po...............

sa madalas nag papapalit sakin ng battery ng tablet At wala pamalit,ganito po ginagawa ko,,

para po sa mga dipa nkakaalam,lalo napo sa mga newbies..

dagdag kita po ito..


materyales:
a.battery ng nokia ung mataas ang mAh like ung bl-4u,bp -4l
mganda ang piliin nyongh brand ung mataas ang mAh(like 3g,3g gold,qq etc..)
b.wire--kumuha sa sirang usb cable or khit saan pwede basta ung maliit lang...

procedure:

1.tangalin ung pinaka plate sa dating battery ng tablet

 2.lagyan ng wire ang neg at postive battery

 3.3.make a parallel connection,ung positive ng isang battery i connect sa positive ng battery,ung negative i conect sa negative ng isang battery(pag PARALLEL CONNECTION,same voltage pero doble ang capasity o mAh,mas matagal malowbat ...)then iconnect ung positive wire ng battery sa positive terminal ng plate na kinuha natin sa dating battery ng tablet,at ung negative sa negative...





DONE


parallel connections:

if you need to increase the amount of capacity available to you, a parallel battery connection is the way to go. Using the prior example, three 12-volt, 200 amp-hour batteries connected in parallel still only produce 12 volts of electricity but will do so for 600 amp hours. Amperage is a measure of the power available.

tnx for viewing...
