A PCB populated with electronic components is a printed circuit assembly (PCA), also known as Printed Circuit Boards Assembly (PCBA). PCB Express Inc provides quick turn PCB assembly services for Printed Circuit Boards Prototype and low volume productions.
tl;dr: Consider using something else to charge your batteries.
This is the printed circuit board of a Hubsan H107-A06 USB charger. It is designed to charge the battery of a Hubsan X4 H107 mini quadcopter from a USB port.
The battery is a single cell 3.7V 240mAh LiPo battery in pouch cell format (Partnumber H107-A05).
Several people habe reported that their batteries don't last long using this charger. It's even worse with 3rd party batteries, which might swell after only a few charge cycles.
LiPo / Li-ion batteries should be charged by a multi-step process, which is usually ensured by a designated charge chip.
en.wikipedia.org/wiki/Lithium-ion_battery#Charge_and_disc...
Many chargers feature an additional step with lower charge current if the battery voltage is too low, to get it back to normal voltage safely.
For a normal 3.7V cell the charge voltage should not exceed 4.2V.
en.wikipedia.org/wiki/Lithium-ion_battery#Specifications
Even if it is not visible, a pouch cell includes a small circuit which makes the cell safer. One feature is to make sure that no voltage too high or too low gets to the battery cell to keep it from exploding or catching fire.
batteryuniversity.com/learn/article/safety_circuits_for_m...
This "charger" is a single sided board, so there is nothing on the other side. There is no charge IC. The charge current is limited by a combination of a diode and a resistor. The diode lowers the USB voltage down to approx. 4.6V while current is flowing. It also prevents the battery from powering the USB port if USB is not plugged in or the PC is off. However, it does not prevent the battery from getting drained by the 220ohm resistor in the LED circuit if USB is not plugged in.
The 2ohm resistor then limits the charge current to 500mA when the battery is discharged to 3.6V.
If the battery voltage is lower than that, the current might exceed 500mA. This is also the exact opposite of what a good charger would do (reduce current when battery voltage is very low).
This thing never switches the output voltage off, which will go as high as the USB voltage (5V) when the current is near zero. A real charger makes sure that the voltage does not go above 4.2V.
Why does the LED switch off when charging is complete? Because the safety circuit in the battery disconnects the battery when the voltage gets too high. Then the output voltage of the charger goes up to 5V and this is sensed by the LED circuit. So this thing relies on the "avoid explosion of battery" safety circuit as regular end-of-charge condition.
This makes me cringe a bit.
Maybe Hubsan uses a special battery chemistry which can handle higher charge voltages. The last time I used this charger I measured 4.3V at the battery terminals of an original Hubsan battery before I unplugged it manually. And maybe the safety circuit in the Hubsan battery is special and switches off as precise as a charge IC would do and is matched with the special battery. In this case charging might work without killing the battery soon.
Anyway, don't connect any other batteries to this "charger". It is not a cool cheap universal 1S LiPo charger.
I personally will not use this thing again, even for original Hubsan batteries.
Added bonus: red wire used for negative battery terminal.
I printed a 14" x 22" poster advertising an event at the San Francisco Center for the Book. They quickly asked if I would print postcards for their mailer. I carved the boxer on wood after a Delittle image. Fun job!

Dear friends an asset close to our heart went down this evening during the scrimmage of Don Edwards in Alviso, CA while seeing his first action of the night. He went down from ~ 20" tipping over with the tripod into the partially dried out salt bed/nasty slush (and possibly a rock?). He suffered internal damage dislocating his CF PCBA (mechanically shifted) and further injuring his CF door (old war wound, ~4ft to tile) he still wanted to continue (electronics fully functional) he had had amnesia(can no longer read CF card) and was forced to remove him from duty.
Niko as I now name him....... was a member of the FX platoon designed by the Imaging Segment of Nikon Corporation will soon meet his makers once again. Unfortunately not just for a routine cleaning but to be decommissioned for a short while for mechanical repairs prior to being returned for duty. He will be missed dearly as he has been subject to much more than most of his brethren have, from -40F to 110F up to 3-4" of downpour for 2-3 hours and physical abuse to just name a few examples.
See you soon Niko and I hope you don't break my heart (bank).

The 2 output transistors, TR11, TR13 are mounted on the aluminum heatsink, and attached to the small green pcbas. TR11 is shorted so both transistors will be replaced with a complementary pair (TIP33C/TIP34C, NTE390/NTE391).
Original main power supply capacitors, 2200mf that will be replaced. Output transistor TR11 (TIP34C, NTE391) mounted to green pcba in upper left corner is shorted, causing the fuse to blow. 4 Diodes below gray capacitors will also be replaced.

PCBA Technology Development
Vigorous development of high-density interconnection technology: HDI concentrates on the most advanced technology of contemporary PCB, which brings fine wire and tiny aperture to PCB.
Strong vitality of component embedding technology: component embedding technology is a huge change in PCB functional integrated circuits. PCB manufacturers have to invest more resources in the system, including design, equipment, testing, simulation, to maintain a strong vitality.
PCB materials that meet international standards: high heat resistance, high glass transition temperature (Tg), low coefficient of thermal expansion, and small dielectric constant.
Optoelectronic PCB has a promising future: PCBA technology uses the optical path layer and circuit layer to transmit signals, and the key to this new technology is the manufacture of the optical path layer (optical waveguide layer). It is an organic polymer that is formed by using lithographic photocopying, laser ablation, and reactive ion etching.
Update the manufacturing process and introduce advanced production equipment.
What is PCB Assembly Services
PCB assembly (pc board assembly) is one of the most important steps in PCB fabrication which includes all the components of manufacturing the complete PCB. There are two ways to make a pc board assembly; namely, Surface Mount Technique (SMT) and Through-Hole Technique (THT). SMT is a circuit assembly technology in which the pinless or short-lead surface-mounted components (SMC/SMD) are mounted on the surface of a Printed Circuit Board (PCB) or other substrate and assembled by soldering through reflow or dip soldering methods. THT uses leaded components with circuit connection leads and mounting holes designed on the printed board, and establishes long-term mechanical and electrical connections by inserting the component leads into the through-holes reserved on the PCB, temporarily fixing them and then soldering them on the other side of the substrate to form reliable solder joints.

FAQs of PCB Assembly Service
What is PCBA manufacturing?
The PCB bare board passes through the SMT patch, and then passes through the entire process of the THT plug-in, referred to as PCBA.
SMT (Surface Mount Technology). It is an assembly technology that mounts surface mount components onto PCB bare board.
THT (Through Hole Technology). It is a through-hole insertion installation technology.
What is PCB assembly?
PCB assembly refers to the assembly of various electronic components on the circuit board through the surface packaging process, that is to say, the empty PCB board passes through the SMT upper part, and then passes through the entire manufacturing process of the THT plug-in.
How much does PCB assembly cost?
PCB assembly cost usually consists of four parts. The cost of components, the cost of tooling, the cost of PCB bare board, and the cost of assembly service. For the same project the second order, the tooling cost is not needed. We ship the goods by DHL or FedEx which entails the shipping cost, if our clients provide their delivery account, then this cost is also deleted.
What is PCB assembly process?
We have high-quality control system and cost control system; components are original binding and sourcing traceable. Quick-response customer support and professional logistical management to meet your demands.
What is a PCB assembler?
First of all, bought all materials including PCB bare board, components, stencil according to customer needs, process the EQ stage and Weld the components on PCB board such as SMD &THT.
