Quid est per puteum PCB et quid interest? typis circuitu tabula? A PCB requirit per foramina vel foramina ad connectendum stratis eius. Understanding the standard through-hole sizes used by PCB manufacturers can help you design boards to meet common bit sizes.

Standard through hole size

Fabricatores PCB mensurae suae magnitudinum foraminis suas habent ut eligat ex exercendis foraminibus, sed plerumque quavis mensura foraminis uti possunt. In genere, artifices PCB diametrum PCB facere possunt per foramina tam parva quam 0.15 mm, comparata ad magnitudinem normalem 0.6 mm.

PCB per foramen mole necessaria

Hoc est altissimam studiorum magnitudinem requisita.

PCB per foraminis magnitudine

Magnitudo PCB per foramen variare potest secundum situm, usum et alia factores eius, unde omnis fabrica PCB offert multas magnitudinum PCB frenum. Most manufacturers can make holes as small as 0.15 mm or larger holes of 1 mm or larger. Cum pro magnitudine foraminis requiratur, debes etiam considerare anulum vel cauculum aeris circa foramen, quod formabit.

How do you calculate rings? The ideal ring is equal to the sum of the diameter of the copper pad minus the diameter of the drill hole divided by 2, which gives the rig the best chance of hitting the center of the pad for optimal connectivity.

Standard through hole size

Non est necesse quodlibet vexillum PCB per foramen magnitudinis in PCB fabricando, sicut vexillum PCB per foramen magnitudine saepe ab opifice ad PCB opificem variatur. Multi autem fabricatores PCB malunt communibus magnitudinibus uti, quas ad mensuram PCB frenum magnitudinum referri possunt. Moles communissimarum una est 0.6 mm, sed 0.2 mm et 0.3 mm etiam communiter.

Type of PCB through hole

Singulis signis uti potes per foraminis magnitudinem ad varias formas PCB per foramina facienda, secundum lavacrum, constructionem, consilium et propositum PCB. Tria genera communissima PCB per foramen sunt:

Patella per foramen

Electroplated through-holes (PTH) are through-holes that run through all layers of a PCB to connect the top and bottom layers. Possis videre PTH ab uno fine PCB ad alterum. PTH ut patella vel non patella. Per foramina non patella electricitatem non agunt, cum patella per foramina electroplata sunt, quod significat electricitatem in omnibus stratis PCB gerere.

cæcus foraminis

Blind holes connect the outer (top or bottom) layers of the PCB to one or more inner layers, but do not completely drill through the board. Precise drilling of blind holes can be challenging, so they are typically more expensive to manufacture than PTH.

embedded

Embedded holes can also increase the cost of PCB because they are difficult to manufacture. The holes are located in the inner layer of the PCB to connect two or more inner layers. Non potes videre materiam sepultam in tegumento PCB.

Considerans autem Rerum

Pauca sunt quae PCB creando consideres. Primum scias quails ratio sit in consilio PCB. The aspect ratio is the PCB thickness relative to the diameter of the through hole, which determines the reliability of the copper plating on the PCB. The higher the ratio, the more difficult it is to obtain reliable plating, which affects the type of hole and plating method you choose.

Foramina emededed vel caeca melius tua PCB ratione aspectum serviant 15, dum PTH bene operari potest submissa ratione 1, 2:1. How do you choose the thickness of PCB copper? Usually, through holes in the outer layer (e.g., through holes) require a thicker layer of copper than the buried through holes inside. Intentione adhibita per PCB etiam aeris crassitudinem afficit. High voltage applications typically require thicker PCB copper than low voltage applications.

By filling program

Interdum PCB per foveas impleri necesse est, exempli gratia, reducere periculum captandi aeris vel electrica conductivity augendi. Some common ways to fill through holes include:

Per tabernaculum

Tabernaculum per foraminis solidiorem iacum super PCB per foramen magis creat quam materia foveam implens. Hoc potest esse optio velox, facilis et sumptus efficens ut per foramina operiatur, sed stilus tentorii per foramina temporis recludere potest.

Per claudebant

Processus per foramen linamentis replet fossam materia non conductiva et persona signans. Through-hole clogging also covers the ring and does not produce a smooth, glossy surface.

per impletionem

Per puteum impletio usus resinae ad foramen perpetuum implendum creandum. Spatiatus per foramen commune est per foveam saturitatem in qua fabrica per-foveam implet materia conductiva, superficiem cupro trahit, ac deinde superficiem parat. This process can route signals to other areas of the PCB.

PCB per foramen applications plating

Manufacturers pluribus technicis variisque artibus uti possunt per laminam PCB applicandi per foramen suam efficaciam efficere. One common method is to use a low viscosity ink that covers the inside of the through-hole to form a conductive layer. Then through the heat curing process to bond the ink.

Altera methodus est electroplatandi, quo PCB in balneum electroplantem accedit. In hoc processu, aeris parietes PCB per foramina cuiusque operit, ex materia etiam conductiva in crassitudine. Haec methodus prolixior et carior quam processus inking tendit, sed etiam certioris vestis et vinculum formare potest.

Sequential drilling blind drilling and deep drilling

PCBS cum caecis foraminibus confici potest dupliciter. Hoc fieri potest per artem laser vel per modum constructionis continuum lavacrum nuncupatum. Using the sequential construction method, pairs of layers can be drilled and electroplated before bonding is applied. Because they have holes at both ends, electroplating is easy to penetrate for chemical coatings. It also allows blind holes to be designed in such a way that they can pass through multiple layers.

Facultas coniungendi congruas compages, exercendi et platandi sequentia efficit ut multiplices foraminis caecae structuras creare possit. Refert an caeca foramen etiam ab exteriore strato transire possit.

Simultaneous deep drilling or reverse drilling is the process of removing any unused copper drum residue from the through hole. Hoc fieri solet, cum signa alta velocitate deformata sunt, dum per tubos aeris inter strata PCB transeunt. Si uti iacuit signo dato in transversalibus longis, multum pravitatis erit.

Proportio aspectum PCB definitur proportio laminae crassitudinis ad diametrum boreholi. Foramina caeca requirunt aspectum rationes 1 ad 1 vel maiores.

Cum alta exercitatio exercetur, profunditas foraminis definitur ponendo bina foramina, quae initium et finem laminis a latere tabulae designant. Obolus diametri ad altam artem computatur hac formula:

Terebra dorsi amplitudo = foramen/codex foraminis magnitudine + 2 x Design regit Terebra magnitudo nimis magna est
