A differentiation between plated-through (pth) and non-plated-

through holes (npth) in your data is very important! Please

export a single drill-file for pth and npth drills, each (e.g.

Excellon or Sieb&Meyer). This rule applies also for blind and

buried vias

Silk ScreenThe marking print eases assembly and additionally allows to

apply a revision number on the printed circuit board. Multi PCB

offers white and black marking print.

Solder MaskPlated-through-holes (pth) can, of course, be exempted

completely from solderstop (e.g. test points, etc.). In General,

you should cover pths with solderstop to avoid solder-bridges!

Heat Sink

Heat Sink help transfer heat to an

area where it can be better

dissipated.

Variation in colors help distinguish

between part numbers and even

V-Scoring is used to prepare printed circuit boards for

mechanical separation. In this process, the PCBs get a pull

linkage, done with precise cutters.

V-Scoring


A

13

Scoring Angels

Scoring is only possible in straight lines, horizontal and vertical,

from and to PCB outer edges We advise to score only PCBs down

to a minimum thickness of 1mm, for stability reasons (thinner

PCBs: notch milling)

Score

• Easy removal of board from panel

• Cost Effective

Route

• Used for irregular (non square) shapes

Score & Route

• Material and Space savings

• Mixed use applications

Cut-Outs as well as Contours are

normally milled.

HAL (Hot Air Levelling) is the most tried surface finish. It is suitable for

standard SMD but for finepitch applications, a chemical surface is

preferable

H.A.L.


A

17

A very common surface with characteristics closely resembling those

of HAL. Due to a faster oxidation process, shelf life depends strongly

on temperature and packaging. Fingerprints on the surface should

be avoided at all costs!

Copper


A

18

A surface very similar to chemical tin, with better attributes at

oxidation and for contact appliances.

Silver


A

19

Chemical gold, as well as chemical tin and silver, has a very

planar surface and good oxidation resistance. It is suited

splendidly for finepitch and bonding (alu wire) appliances.

Chemical gold has replaced carbon print for keyboards.

PC / PCI slots are f.e. used to connect printed circuit boards

directly to main boards (motherboards). It is differentiated

between PC-AT standard with a grid space of 2.54mm and PCI

standard with a grid space of 1.27mm between the gold

fingers.

PC Slots


A

21

ChamferingChamfering of the gold fingers is to be avoided at all costs,

therefore they need to have a spacing of min. 0.7mm from the

PCB edge. We advise you to connect the gold-fingers with 200µm

tracks to the edge (see sketch). Due to the production process,

gold fingers are always connected with the edge like this.10/2/08 Select Circuits Presentation / Created by Joe Lara / Document # 001-001-A
