ISE-NIN-BOM-REV1.0.1.pdf. updated by BC on 24th.Sep.2022

Here is my mouser project link which matches with the BOM v1.01 (24th.Sep.2022)

I added few spare parts for the tactile and the tactile caps. please read the notes for the parts in the project.

https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=3E3D0F0CF3

There are no IC sockets added in this mouserproject, eBay offer this cheaper for this quantities.

some notes:

the tactiles are out of stock by mouser - use tme.eu or other supplier.

for the 3900pf caps, you can use polypropylene caps - do not use polyester

use eBay or tme for the SMT caps to safe money

Issues: have a look at the ISSUE lists below for changes!!

the part number for the trimmer at mouser isn't correct (more information - it’s described in the "Issue" list)

Build guide: ( in progress)

Power supply PCB (PSUb) -

1. install the resistors and diodes
2. install the ceramic capacitors (not the electrolyte caps yet)
3. install the TO-220 regulators (IC4, IC5, IC7), the black isolated regulators do not match with the pcb holes, its not important. bend the pins as short as possible that they can be soldered from the rear-side of the pcb
4. install IC3 - I prefer without a socket for better thermal regulation, but should be fine with a socket too.
5. install the electrolyte caps
6. install the LEDs - LED orientation - the square pad is ground (short leg) its the flat side of the LED designator
7. install the fuse socket and MTA 156 2pole header
8. install the DC-DC bricks (IC1, IC2)
9. Double check the IC orientation and part values, Capacitor polarity 
10. wash the PCB carefully and let they dry over night 
11. optional - use a bench psu for testing with current limiter 12v/200mA don't use a smaller current limit to avoid problems while start, the 200mA is a given value without any devices connected
12. must do: all LEDs must be on, check against the given PCB voltages - all voltages must be correct

first test on a bench PSU with current limit at 12v/200mA

Breakoutboard (BB)

Start with the SMT parts on the rear side and IC4.

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 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, 16pin IDC connector
6. wash/clean the pcb before you install the USB socket, MIDI socket, Audio jacks
7. wash/clean the pcbs carefully with respect on ESD safe handling 
8. install the USB and Midi Socket, Audio jacks
9. Double and triple check the IC orientation

Mainboard (MB)

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

you need an ESD map and ESD safe handling (tools) - because the uController is preinstalled and can be destroyed due to wrong handling.

I really prefer to use a Soldering frame - Ideal Teck PCSA-4 (the MB and HB-pcb fits perfect)

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)

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 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:

1. install the 12mm spacer on the HW.board,
2. then put on the mainboard the opposite part
3. then put the boards together and fix the pcbs with few screws on the spacers
4. then solder the 10pin dual row header/socket all pins - solder both parts completely before you remove the pcbs again (otherwise some pins can be accidentally removed)
5. clean these solderpoints with eartips carefully.
6. remove the screws and disassembly the pcbs
7. --------
8. install the sliders on the Hardware Board, and carefully solder them - pin by pin - as described in the above table (do not overheat the parts)

finally we can move to the last steps which can be done in different ways

9. install the tactile switches and solder these, solder 1-2 per switch - not all pins together to have less heat on the part.

10.  the last parts can be installed with one step or step by step - but in this case, you have to remove the frontpanel a few times. (customers with experience from DDRM/Kijimi can try to install the pots, OLED, LEDs, tactiles in one step)

11. cut/remove the locker pin on the potentiometers 

12. the potentiometer must be installed with the front panel attached for best alignment

13. the potentiometer have to sit on the pcb - do not try to to install the potentiometers in a higher position (or you can run in problems with the knob height)

14. there are 2 options how to do that.. but my shown option should be the best with separate nuts (no wobbling pots)

DO NOT try to install the nut on the frontpanel side !!  install a nut as shown below .

LEDs:

here´s an example how to install the LEDs easily:

Put the HW board on the Mainboard:

install the spacers (12mm spacer between HB and MB) put the MB on the HB - then solder the headers on the pcbs

mount the bracket on the BB pcbs with 2 screws.

testing

Test the PSU without BB - on a bench psu with current limiter 200mA
