here´s an example how this has been installed by me, add some solder on one pad and heat up this pad while you move a capacitor with a tweezer to the location, then add some solder on the other side too, normally no extra flux (fluxpen) is needed but depends on your skills. 

1. install the

...

1. SMT capacitors and IC4 (the dot on the PCB is pin1)
2. install the resistors - solder all pins.
3. install the ceramic capacitors - solder all pins
4. install the IC sockets - standard IC sockets preferred - solder all pins after you have checked the alignment
5. install the power socket, MTA156 header,

...

1. 16pin IDC connector
2. wash/clean the pcb before you install the USB

...

1. socket, MIDI socket, Audio jacks
2. wash/clean the pcbs carefully with respect on ESD safe handling 
3. install the USB and Midi Socket, Audio jacks
4. Double and triple check the IC orientation

Mainboard (MB)

the heart of the ISE-NIN must be build really carefully !!

...

1. install the SMT capacitors as before described in the Breakoutboard section.
2. install the resistors - solder all pins.
3. install the ceramic capacitors - solder all pins
4. install the IC sockets - standard IC sockets preferred - solder all pins after you have checked the alignment
5. install the Transistors/regulators, quartz - do not overheat the pins here
6. install the Filmcapacitors/Electrolyte caps and solder one pin - align the capacitors before you solder the second pins.
7. install the EDGE connectors - solder only at top and bottom a pin and check the alignment, solder from left to right to minimize overheat problems with the connectors.
8. don't forget to solder bridges at the white flat line on the EDGE cards as shown in the above table.
9. check the soldering on the EDGE card pins carefully for shorts/solder bridges.
10. wash/clean the pcbs carefully with respect on ESD safe handling 
11. install the ICs 
12. Double and triple check the IC orientation ( tip: mark with a pen all ICs which did you checked)

do not install the 10pin headers/pins yet (we put the header on the pcb later - when we have finished the controlboard - to get the best alignment)

do not install the OLED yet - to avoid damages and dust on the screen

Hardware Board (HB) (sometimes called Controlboard)

1. we start with the PCB side with the IC sockets, the rear-side which is connected to the Mainboard (as shown in my pictures)
2. install the SMT capacitors as before described in the Breakoutboard section.
3. install the resistors - solder all pins.
4. install the ceramic capacitors - solder all pins
5. install the IC sockets - standard IC sockets preferred - solder all pins after you have checked the alignment
6. install the transistors - do not overheat the pins here
7. wash the pcb carefully with isopropyl and soap with handwarm water up to 50C Celsius.
8. Install all ICs when the pcbs are dry
9. double and triple check the IC orientation ( tip: mark with a pen all ICs which did you checked)

do not install the OLED yet - to avoid damages and dust on the screen

do not install the headers /pins yet

do not install the LEDs yet, no sliders , no potentiometers for now !!

because you have to clean/wash the PCBs PCBs before we can proceed - jump to Voicecard assembly until the pcbs are dry. (normally overnight in a warm room)

Voicecards:

assemble the voices until the other pcbs are dry  - do not install the trimmers until you have washed the PCBs!

1. install the SMT capacitors as before described in the Breakoutboard section.
2. install the SMT ICs
3. install the resistors - solder all pins, do not install the Tempco Resistor yet
4. install the ceramic capacitors - solder all pins
5. install the IC sockets - standard IC sockets preferred - solder all pins after you have checked the alignment
6. install the Transistors/regulators - do not overheat the pins here
7. look in my above guide - about the 240pf capacitors - maybe you have to select or match something - its not needed but for some builders just a notice
8. install the Filmcapacitors/Electrolyte caps and solder one pin - align the capacitors before you solder the second pins.
9. wash the pcbs as described before 
10. when the pcbs are dry - install the Trimmers
11. install all ICS
12. install the Tempco resistors  - this must be thermal connected, use thermal paste 
13. double and triple check the IC orientation

Hardwareboard part 2:

install the 12mm spacer on the HW.board, then install the 10pin dual row header/socket - solder both parts to each pcb, clean these solderpoints with eartips carefully.
