Standard

1.Easy to use and quick to get started

2.The process supports design scales of 300 devices or 1000 pads

3.Supports simple circuit simulation

4.For students, teachers, creators

Profession

1.Brand new interactions and interfaces

2.Smooth support for design sizes of over 30,000 devices or 100,000 pads

3.More rigorous design constraints, more standardized processes

4.For enterprises, more professional users

PCB AND MY PERFORM

DONE TOP.jpg DONE BOTTOM.jpg

IMPROVEMENTS

i1;i3 c12 and R9 for # impedance decrease intentionally # changes their values from oryginal HILAND from 10uF;47K ohm to 470nF and 1M ohm

i2 added optional SMD pads for unpolarised 10uF cappacitor

This improvements gave better range width to small cappacitors measure, which will be show on the picture.

HILAND 11.jpg HILAND 12.jpg

IMPORTANT MODIFICATIONS

M7 instead 1800 pF cappacitor replaced to 1377 pF - THIS CHANGE MUST BE OVERWRITE INTO THE PROGRAM REFERENTIAL CAPPACITANCE VALUE (2 BYTES CHANGE)

M8 R5,R6 instead 2000 ohm and 200 ohm mounted 2213 and 219 ohm - THIS CHANGE MUST BE OVERWRITE INTO THE PROGRAM REFERENTIAL RES. VALUES (4 BYTES CHANGE)

ASM CHANGES.png

OTHER NOT IMPORTANT MODIFICATIONS

M1 - r14,r15 instead 5k1 res used 4k7 - doesn't matter

M2 - Instead 9012 used BC557 (DIFFERENT FOOTPRINT!)

M3 - 8050 replaced to BC547 (DIFFERENT FOOTPRINT!)

M4 - 4148 diodes replaced to any diode to pretect before over voltage peak

M5 - inductance 82 uH replaced by 68uH - just change resonance to higher freq.

M6 - c9 1800 pF replaced to 1000pF - the resonant circuit going to higher freq.
