The document describes a DIY PCB exposure box created by Junjon L. Santuyo. The exposure box uses UV light to expose photoresist on printed circuit boards for a certain period of time, which is important for accurately etching the circuit designs. Santuyo discusses how the exposure box allows electronics enthusiasts to experiment with different UV light timings to create high quality PCBs through the photoresist method. The results of Santuyo's low-cost, minimal tool process are adequate for personal use and cover all PCB making needs.

1. PCB EXPOSURE BOX
BY: JUNJON L. SANTUYO
DESCRIPTION:
Exposure Box is a lighting machine to
expose unnecessary part of the circuit just like for
printed circuit board in electronics
PROBLEM DESCRIPTION:
As an electronics enthusiast, I want to
make my own PCBs. I am impressed with the
quality of the photoresists method. Its really
accurate if its done properly and the results are
really nice. Photoresist PCB needs to be exposed
to UV light for a certain amount of time period;
that means it wont etch well if it get overexposed
or underexposed. But to begin and do the
experiments with the UV light timing, we first need
a UV exposure box to expose the PCBs.
Innovation is nothing more than taking an
already existing idea and making it better.

RESULTS:
My DIY PCB manufacturing process is
working reasonably well, so its time to share what I
have learned. This covers printing, exposing,
developing, etching and drilling/cutting all the way
to a finished pcb. My process is an extremely low-
cost one, with minimal tools and supplies needed.
The results are not perfect, but very much
adequate for my purposes, and covers all of my
pcb making needs.
WAY FORWARD:
I very much enjoy making my own
circuit boards. Its a satisfying process that
ties together my love of electronics with
materials I used back in my art school
days. Its also the most accurate way to
build a circuit short of sending away to a
PCB manufacturer, and its much more fun.
DRIVERS TO
INNOVATION:
Probably everyone electronics
hobbyist is dreaming about fast PCB
prototyping method. Some of you are just
ordering professional made PCBs, that is
not always worth of cost, other are using
easier way Laser printer toner transfer
technique which is not very accurate, third
option is more advanced ultraviolet light
exposure of photo-resist coated PCB
through film mask. This gives pretty good
quality at reasonable price and doesnt take
much time
