CIRCUIT BOARD LAYOUT and DESIGN C.A.D. - just one of our services

Please note - we do NOT " mass-manufacture " circuit boards. We do however, design the circuits and

can facilitate the layout, prototyping in either Single-Sided or Double Sided P.C.B. to your specifications.


A more detailed drawing of a six-layer Circuit board

Above is a " reasonable explanation " of a six-layer PTH (Plated Thru-Hole) PCB (Printed Circuit Board).
Note the layer identification names.


A drawing of a multi-layer Circuit board

Above (Fig 1a) is a " quite exaggerated " exposed symbolic picture of a multi-layer thru-hole printed circuit board.
This is only a representation,   whereas in reality, the process is quite involved and does not have parts on it.

 As stated, yes, it is an excellent idea to condense a circuit into the smallest possible size thus saving on  
 the board's physical dimensions, however....in doing so, there are strict "electronic" rules that govern the 
 passage of electrons along a particular circuit board track which may induce a new headache that is called 
 cross-talk or "electronic noise" from one circuit to another, please be very aware of these constraints and 
 there are trade-offs in any circuit board layout or design, speed and noise immunity are the most sought after  
 features requiring " ground planes " to shield or rather contain and reduce "cross talk" or high frequency 
 " parasitic " oscillations from one track through a circuit board track to another.

Major billing update April 26th 2019
 Labour rates for al lREPAIRS and / or all SERVICING WORK is billed at $ 150.00 per hour or 
 ( 150ドル divided by 60 = $ 2.50 per Min ) plus 10% GST. We bill for actual company time spent.
 This equates thus as for 1 hour, 150ドル plus 10% GST = 165ドル including GST or if we calculate 
 in minutes, whereas $ 2-50 per Minute + GST = $ 2-75.So, therefore 47 minutes = 47 x 2ドル.50
 equals 117ドル.50 plus 10% GST (11ドル.75) = 129ドル.25 total including GST. Some jobs take minutes.
 This increase today, April 26th 2019 is our first price increase since May 1st 2002 
 (ie: 17 years to cover ever increasing costs and overheads and updating service equipment.
 Please Note : Labour rates DO NOT include any materials or components we actually stock 
 or we have to "order-in" NOR DO they include any GST component. 
 GST is added and charged at 10% of the final sales price, this includes parts, labour and freight.
 Please also note :- Time taken is as with some jobs is calculated in months, weeks, days, 
 hours and / or minutes, this is depending on complexity and the availability of a accurate circuit.

Updated April 26th 2019
 Please be aware, we are not a " results only company ", that is to state as in " only " being paid "only" 
 if the result is goods or equipment works. We accept "your goods" for repair or service in good faith, however 
 if it is found at some stage during the repair(s) that the said item (s) for repair or service are not going result 
 in a positive working outcome, either due to the age of item(s) or component(s) that are " still now " available
 in stock, we will advise you of the costs so far in arriving at this conclusion. There are no "Free lunches".
 If we have to leave our premises and obtain parts on your behalf, making sure the parts are the correct size, 
 or correct dimensions and equal to or better than the original, then this service is charged at the same rate 
 as 150ドル per hour + GST, 2ドル.50 per minute plus GST, this accounts for driving time to and from a suppliers 
 premises to inward goods inspect the parts / components and pay for them on your behalf. This cost is borne 
 by you the customer and vehicular running costs based at 1ドル.80 cents per kilometer there and back to our office
 are to be applied. So, recapping, time spent collection the parts, ( to and from ) plus kilometer costs + time.
 
 All company time is accountable for. This is only fair as where you work, you would not like be NOT PAID as a 
 result of a project or job not working out right and your boss telling you, "tough luck mate.... it did not work so
 no pay for the hours you wasted on trying to get it going". Resolution Meeting: August 12th 2012 7:35 pm .
 New resolution and meeting, ( after maintaining a 100ドル per hour from May 1st 2002 ) until today April 26th 2019, 
 we have caved in to pressures after 17 years, to raise our labour rates to 150ドル per hour, plus GST. This is largely  
 to do with increased running costs of which we can no longer absorb and our continued investments in new and
 current technologies, technical electronic measurement tools, Digital Storage Oscilloscope, CRO's as well as a
 far higher than any previously maintained stock level overheads. Being a Lawyer or Barista would have been a far
 better paying career and charging between 6,000ドル to 10,000ドル per day with no parts to stock is outstanding. 
 Resolution Meeting: April 26th 2012 9:30 am .

 We require payment for company time spent on your behalf working on your goods or equipment irrespective of  
 the final results that the item(s) in question are working. We strive for perfection in servicing and repairs, however  
 there are times where component tolerances change over the years, often resulting in undesirable board faults 
 that are "hard to diagnose" along with often inherent stray capacitances and weird parasitics etcetera, plating 
 "growths and spurs" or "Whisker formation" that creep into circuit boards over time. Many companies, including 
 NASA have notes on this strange and very undesirable phenomenon.
 Other servicing prblems to be remembered are the adhesive holding copper tracks and pads (aka lands) onto a 
 PCB. Over time, the copper foil "adhesive" between the fibre glass board does break down to a gritty powder, 
 thus if a circuit board is quite old, it will inevitabley become a major issure or problem for who ever solders or 
 repairs that "older" PCB ( Printer Circuit Board ). That is just one "age old" issue to seriously contend with. 
 Copper tracks and pads tradionally do not like being heated too much and the net result of the heat from a hot 
 soldering iron, it can and does become annealed or brittle and fractures. This too is simply not good.
