Ring solders make it possible to miniaturize print circuit boards!
When soldering at the other side as shown at picture B, there shouldnft
be much problem to shorten the height because you could solder by dipping
into the solder bath.
However, it is not easy to actually solder the contact pin inserted into
the circuit board at the same side. It is not likely when dipping into
solder bath because solder will stick on to the portion where the socket
of the contact pin matches and fattens the pin. Also, this method is not
recommended because solder will over cover the surface of the contact pin,
which are usually covered with gold and other metals to reduce the resistance.
Therefore, you will need to hand solder or use a soldering robot to solder each pin one by one. If there are only few pins to solder, you might not take time but if there are more pins, you will need a long time to finish this process. Think of printing cream solders, printing solders are still uncertain when thinking of its strength due to the limited quantity of solders.
So what should we do now?
Using gWa!Penh is another way to insert ring solders into connector pins. gWa!Penh eases the inserting process more than using tweezers.@ To insert less than 10 pins, it takes just the same time as when using the automatic inserting machine.
If you donft want to rely on hands and if you need to produce same items in large quantity, please ask us for the automatic inserting machine.
