Documentations are in the paper form. The good part documentation is the obtained tracing of schemes of cards and complexes. Such documentations mainly have and assembly picture card (the hand is drawn).
On Your requirement scann the wanted documentation and sends you (JPEG / GIF pictures). Price
struck out documentations is 25 HRK - 80 HRK (3.33-10 eura). This is super profitable. Requires know that considerable times lost that gets the adequate scheme. Our struck out documentations in majority cases (90 %) have and assembly scheme these consist of and correct counter beside the every element (are written the green color). Thus has been enabled the simple and fast the finding of elements which has been drawn in the scheme. Aside from this two-sided board have are drawn lower conduits in blue, and upper in the red. Thus are conduits on the assembly picture of two-sided bard also easy for the tracking.
Example struck out assembly schemes:
Picture is intentionally are presented in the small resolution and large compression in order to this page is small.
All sent pictures will be are scanned in 300dpi the resolution and beside the optimal compression.
Smaller documentations or parts of larger documentations can get via email. Remain on CD.
Besides sells existing documentations, can order and making assembly and electric schemes of your card. If is the sufficient alone assembly scheme, can order the making only she. Work the documentation board which have no internal layers of guidebook. Little plates which has SMD element treat as if have internal conduits this for such do not work the documentation. Prices service can find in the price list.
How always men which have wills and knowledges that the alone making of documentation of single complexes will describe you way for the making documentations. As examples let them take the upper card.
The basic method:
Whitepaper cover the side soldering and press him good on pins (that perforate).
Get off the paper down and with the dark thin pen mark holes and position of elements. Holes mark with cross. (+) conductive holes with the x (x). Elements only minimally sketch without marks.
Put the new Whitepaper across these sketches, and the sketch easily attach. On the glass table (with the illumination from below) copy the pencil position of elements, all pins and holes. Thus have got the assembly scheme.
Separate the sketch and turn the assembly scheme. Make red pen zatočkamo all pulls out (the side soldering)
Blue the thin pen draw conduits based on the original.
Turn the assembly scheme this beside elements and pencil write in marks. With green pen write in position number elements using some from methods marking (the numbering along orders or along columns). Now have the complete assembly scheme with numeriranim elements. Numbering of elements are important because of the managing in the tracing of electric scheme. How some cards can have many elements of same value or the mark, easily could will happen the error by the tracing (wrong connecting or the duplexing).
Before the tracing of scheme good is the assembly scheme will become rich functional sketches inside single elements. Npr. correctly draw in the start and by coils of transformers, electrodes on semiconductors, functions of integrated circles etc. All easily let him draw in the pencil.
In the end strike out the electric scheme. If do not know from to start, get a few advice: If the board has the power supply, strike out the power supply and put labele (e.g. +12V, VCC, GND etc). How the almost every card has entry and exit signals, good starts with the drawing schemes from them. If is number the entrance greater than the number output, start from the output. In order to can follow conduits, board look at from the assembly side, and the additional illumination bottom enlighten conduits. If own scanner can, adjusting of parameters of scans, get the picture of elements and conduits (the above example). Then can the scheme strike out following conduits on the screen. Obligatorily put position number beside the element in order to him after more easily locate.
If are not the satisfied appearance or the being easy to survey schemes, cross out the scheme on the other paper or the write in some program for the drawing scheme (Eagle, Tango, Orcad similarly.). And that's it.
Keep in mind, that the time necessary for the getting of complete documentation grows proportionally with the square of the total counter elements on the card. Tracing of integral scheme one screen (one-sided little plates of dimensions 200 * 300mm) can last up to 2 day.
The basic method does not look for special and costly device. Instead of the glass table with the illumination (necessary for the copy hole) can stand in good stead and window (during the day) or glass doors with the suitable contra light. The additional advice, who can apply, will depend about your possibilities and wishes:
If you on disposal the copyr maschine, try photocopy foreign conduits. Adjusting blackening possibly gets excellent sketches of conduits in the moment. At the sufficient good contrast was able this copy overleaf will become rich the site scheme of elements. Thus have jumped over the copying of positions of holes and drawing of conduits. Possibility of getting quality sketches of conduits depends on and contrast of printed board.
If have computer with the scanner, can scan the board (adapting factors scans), the picture and prints. Thus have got some similarly as at photocopying. Scan can replace the painting with the digital camera. At this needs pay attention that must paint without the flashgun and beside the even diffusive lighting.
When have the digital picture in the computer has been able load as the rear picture in some program for the vector drawing. Towards this model can manually to line complete conduits and solder places these then these conduits print. Warning: drawing of conduits computer last multiple longer than the drawing with hand.
Recommend that enlarge dimensions cards (50-100 %) in order to what more easily enter marks beside elements on the assembly scheme. Magnification can make simple magnify the first sketch of pins and elements using photocopyr.
If have two-sided printed conduits then upper conduits draw make red the thin pen. Way of conduits below elements were able investigate with the examiner of diodes (zumerom). In the event of the insecurity best is temporarily disassemble element which hides upper conduits.
Pens for the drawing has been needed waterproof and thin. Usual thin flomasteri has removed the diffusion (who can will happen immediately or gradually during the year).
Acquired documentations beware on the dry place. Humidity can provoke the spilling of drawn conduits.
Want you a lot the success in making your own documentations!
