How do I re-solder the micro usb power receiver back on to my cousins digital2 7" tablet?


This is a pretty delicate solder but if you are comfortable then all you need is a soldering iron and some solder with a flux core. Warm up the iron until it can melt the solder and melt the two together. I do have to say that it is not that you can't do it but I have 18 years of soldering experience in telling you this wont be an easy one.

Repair solder joints on tascam 52


You need a small soldering iron no greater than 15 watts. Plus some good quality radio solder.
The operation is simple. Get the iron hot so that it will melt the solder. Then find the dry joints on the unit. All you have to do is heat the solder joints till they melt. Be careful not to let the solder flow into other joints and make connections that should not be made. If you do they will need to be undone using a de-soldering tool, which you can get the same time as the iron. I like the red vacuum bulb type best. If you need to add more solder do so while the iron is on the melted joint. Only apply the iron for a short time to avoid heating the components or damaging the solder tracks. Just to get it to melt.

I have a 1998 dodge grand caravan and my gauges won't come on


Im a computer Geek, not a car mechanic; My mechanic took the Guage Cluster Out and Insisted: I NEED a new one; Not True and Its a V.E.R.Y. Easy fix.

1.Remove Srews.
2.Unplug the main instument panel power supply plug.
(there may be a few bulb sockets that need to be disconnected, as well).
3. Don't Bother Examining the Contacts, Opposite the Plug In Socket.
4. Heat a Soldering Iron (Buy a Cheap 9.99 Soldering Iron, Solder, Flux) kit
(sold at Radio Shack; You want the thinnest Solder and USE THE FLUX. Not using flux, and/or 'cold soldering' is most likely the reason the solder cracked).
5. The cracks are so tiny you cant see them, all of the time, even under magnifier, so just brush, or dip your finger into flux and smear it over the 8 or 10 pins.
6. Heat one by one until original solder melts on each of the Power Socket Pins.
7. Let Cool, Wipe Clean..
8. Flux all Contacts Again,Flux heavily, heat an extra thin solder on the tip of the iron, not on the circuit board and try to drip a small blob of solder onto each of the your 8 to 10, or so, etc. contacts.
11. Make ABSOLUTELY CERTAIN, no 2 contacts are touching each other; if so, melt the solder off of one or both of the two touching one another.

I am A computer repairman who has made a small, side business, of soldering contacts, on guage clusters, for as many repair shops, in my community,who wish to pass savings onto their customers. I charge $25 per and hope the shop owner passes their savings onto the consumer.

So Far? 95% of the clusters i have soldered, were repaired by this method. Its so reliable: if It doesn't work, there's no charge~!

I just bought the soldering gun but the instructions on the package aren't very useful how do i use the gun?


A soldering gun is used much the same as a soldering iron for melting solder mainly to connect electronic components to circuit boards. To use it you plug it into the electricity mains and press the trigger. This causes the metal tip to heat up. Allow a minute or so for it to reach full heat and press it to the components you want to solder together. When they heat up press the solder against them. The solder melts and runs on and between them forming a bond. Remove the soldering iron and release the trigger. Once the trigger is released the gun starts to cool down again.

If you've used a soldering iron before you'll probably find the gun more awkward as it cools down every time you release the trigger. It's really only useful for quick jobs where you're not going to need it every few minutes. For other jobs where a lot of soldering is involved a soldering iron is better. The advantage the soldering gun has over the soldering iron is that it heats much faster for quick jobs.

My headphone jack is bent and so the headphones barely work.


THE BEST WAY TO DO THIS IS TO GET THE REPLACEMENT JACK FROM AN AUDIO OR MUSICAL SUPPLIES SHOP.. ONCE YOU HAVE THIS CUT BACK THE CABLE OUTER SLEEVE TO SHOW THE CONNECTORS AND CABLES ON THE JACK..GET A SOLDERING IRON READY WITH SOLDER.. STRIP BACK A SMALL AMOUNT OT THE CABLE SLEEVE TO SHOW THE WIRES THEN STRIP BACK EACH OF THE CABLES AND TWIST THE ENDS SLIGHTLY..GET THE SOLDERING IRON HOT AND TOUCH THE WIRE TO THE END WHILST BRINGING TEH SOLDER TO THE WIRE TIP. IF TEH IRON AND WIRE ARE HOT ENOUGH A SMALL AMOUNT OF SOLDER WILL MELT ON TO THE WIRE TIP.. DONT HOLD THE WIRE TO LONG OR THE HEAT WILL MELT THE PLASTIC COATING., DI THE SAME FOR THE OTHER WIRE.THEN UNSREW TH NEW JACK YOU SHOULD SEE EITHER TWO OR THREE CONNECTORS MATCH UP THE NEW WITH THE OLD ON THE CONNECTOR AND SILDER ON ONE BY ONE THE SAME WAY JUST HOLD THE WIRE AND IRON TO THE PLATE AND HEAT WILL CAUSE THE SOLDER TO ATTATCH TO NEW CONNECTIONS..MAKE SURE YOU HAVE PUT THE SLEEVE ON THE WIRE BEFORE YOU SOLDER OR YOU MAY HAVE TO TAKE IT OFF AGAIN TO PUT THE JACK BAK TOGETHER..TAKE YOUR TIME WIT THIS AS IF YOU TRY TO HURRY THE SOLDEDRING PART IT CAN BE MESSY AND NOT TAKE PROPERLY AND CAUSE BREAKAGE AWAY LATER IF THE JACK IS PULLED.. ONCE THE WIRES ARE SOLDERED ON TURN OVER THE GRIPS AND IT SHOULD WORK FINE.. I USUALLY GO FOR THE METAL TYPE JACKS AS THEY ARE STRONGER AND EASIER TO SOLDER.. GOOD LUCK A...

The positive wires are snapped how do i fix it


Hello gosecoa,

The tinsel leads can usually be soldered back on OK. You may need to remove a small amount of the sleeve. Make sure that your soldering iron is clean and well tinned. Hold the tinsel lead gently in position with a nonconductive tool and apply the soldering iron to the edge where it meets the solder pad on the back of the sub cone. After the solder has melted (usually you won't need to add any additional solder), remove the iron first and continue holding the lead into place until the solder hardens.

Hope this helps.

No longer melts solder with tip....


You have burned out residue on the tip. Clead it off with a damp cloth when the iron is hot. If this doesn't get it all, use steel wool. Immediately afterwards, get flux & solder onto the tip or it will get coated again.
