+ <p style="justify-content: center"><strong> group assignment: characterize the design rules for your PCB production process <br>
+ individual assignment: make an in-circuit programmer by milling and stuffing the PCB, test it, then optionally try other PCB processes </strong> </p>
+
+ <h4 style="border-bottom: 6px solid yellow; background-color: lightgrey" > <strong>Introduction </strong> </h4>
+ <p style="justify-content: center"><strong> The PCB manufacturing process is very important for anyone involved in the electronics industry. Printed circuit boards,
+ PCBs, are very widely used as the basis for electronic circuits. Printed circuit boards are used to provide the mechanical basis on which the circuit can be built.
+ Accordingly virtually all circuits use printed circuit boards and they are designed and used in quantities of millions.
+ In this week we have study the PCB production processes then we have to make an in-circuit programmer by milling and stuffing the PCB. After this we have to test this PCB. <br>
+ The machine available for PCB milling in our Fab Lab has folowing specification:<br>
+ Manufacturer: Roland <br>
+ Model: SRM-20 <br>
+ Specifications: 203x152x60 mm, 1800 mm/min, 0.001 mm/step, 7,000 RPM <br>
+ Applications: Precision three-axis machining, including PCBs down to 0.25 mm feature size, and machineable wax to make tooling for molding and casting
+ </strong> </p>
+ <br> <br>
+ <h4 style="border-bottom: 6px solid yellow; background-color: lightgrey" > <strong>Group Assignment</strong> </h4>
+ <p style="justify-content: center"><strong>In group assignment, the task for this week is to characterize the design rules for PCB production process.
+ So we five member in group, trying to machining of PCB usign SRM-20 i.e. PCB milling machine available in our Fab Lab. So,lets see how we develop the PCB.

+ <h4>a. DC Fan</h4>
+ <p style="justify-content: center"><strong> The fan is used to sucks the smoke from the kitchen, exhaust it into the atmosphere. Here i have to select the fan, which is work on solar power. so the DC fan is selected.
+ The propose DC fan have this specification: <br>
+ Type: Axia Fan, Voltage:12V,Power:3W, Current:0.25A, Speed:2400 RPM, Size: 12x12x2.5cm,Air Volume:85CFM, Noise Level:35db </strong></p>

+ <h4>b. Battery</h4>
+ <p style="justify-content: center"><strong> Batteries as electrical storage medium, are very important part of this system because it have to provide the energy when there is no sunlight
+ So here i have to used sealed lead acid battery of rating 7.5 AH/12V. </strong></p>

+ <h4>c. PV Module</h4>

+ provide higher power than a single solar cell. The PV module are available in the power rating from 3 watt to 300 watt. They really form the basic building block
+ of PV system as power generating unit. Here we required a energy from PV module for Battery Charging of around 7.5 AH. The power of battery is used to run a suction fan of
+ blower.so here i selected the PV module of rating 10W/12V. </strong></p>

+ night time applications. So here the protection of batteries is required from over-charging, over-discharge as both of these damage the batteries and reduce their lifetime.
+ so the device which protect the batteries is know as charge controller. MPPT is used to ensure that PV module is supplying maximum posible power to the systems.In the absence of
+ MPPT, the PV module may work in sub-optimal conditions and may not generate power to its potential. The charge controller and MPPT are club into single electronic device

+ a processor, memory and input/output (I/O) peripherals on a single chip. A microcontroller is embedded inside of a system to control a singular function in a device. It does this by interpreting
+ data it receives from its I/O peripherals using its central processor. The temporary information that the microcontroller receives is stored in its data memory, where the processor accesses it and uses
+ instructions stored in its program memory to decipher and apply the incoming data. It then uses its I/O peripherals to communicate and enact the appropriate action.There are a number of technology and b
+ business considerations to keep in mind when choosing a microcontroller for a project.Beyond cost, it is important to consider the maximum speed, amount of RAM or ROM, number or types of I/O pins on an MCU,
+ as well as power consumption and constraints and development support. </strong></p>
