 === Soldering SMA Connector to Coaxial Cable ===
-Below shows the easiest way to solder an SMA connector to the end of the coaxial cable. This can also be done using standard SMA wire connectors but it more difficult and more prone to breaks. '''Make sure to test for shorts in the coax cable before plugging in and powering up the DAQ PCB. If a short is present, permanent damage can be done to the DAQ PCB.'''

 If you decide to have the through-hole components assembled by an assembly house you can skip this section. Below is a picture highlighting the necessary through-hole components that need to be soldered in order for the DAQ PCB to function properly.

-=== Filter Edge Blackening (Suggested) ===
+=== Filter Edge Blackening (NOT USUALLY NECESSARY) ===
-While not strictly necessary, we suggest blackening the sides of the dichroic and emission filters. We have noticed that if a scope has light leakage issues (excitation light making it to the CMOS imaging sensor) blackening the dichroic and emission filters' sides fixes the issue.
+Our current version should not need this, but if you have light that leaks through the miniscope (i.e., you can see light being recorded even when the bottom of the miniscope is entirely covered), then blackening of the filters can fix this problem.  We have noticed that if a scope has light leakage issues (excitation light making it to the CMOS imaging sensor) blackening the dichroic and emission filters' sides fixes the issue.
 Optical companies may be able to blacken the sides for you but it is also easy to do yourself. We have had the most success using Rustoleum Flat Black Enamel with a thin paintbrush.

	If you have the newer version of the DAQ PCB (version 3.x) you can disregard the through-hole and coax cable connector soldering described below. The DAQ PCB v3.x comes fully soldered and just needs the EEPROM inserted and switch/jumper configuration set correctly. The coaxial cable from the head mounted scope will connect to the J4 (SMA connector closest to the center of the DAQ PCB) connector.

−	We generally have all surface mount (SMD) components assembled on the DAQ PCB by a third party PCB assembly house leaving only the through-hole components to be assembled in lab. It is possible to have the assembly house place both SMD and through-hole components but it is more expensive and through-hole components are relatively easy to solder. A good through-hole soldering tutorial can be found [https://learn.sparkfun.com/tutorials/how-to-solder---through-hole-soldering here].
