PCB drilling is a process of PCB plate making, but also a very important step. Amin’ny ankapobeny ny fitrandrahana ny birao, ny filan’ny tariby dia ilaina ny manao lavaka, ny filan’ny rafitra, manaova lavaka hanaovana toerana; Ny fitrandrahana birao marobe dia tsy malaza, ny lavaka sasany milevina ao amin’ny solaitrabe, ny sasany eo amin’ny solaitrabe etsy ambony dia mahazo, ka hisy fandavahana roa.

Ilaina ny fandavahana handentehana ny fizotry ny varahina, izany hoe hametahana ny lavaka amin’ny varahina, mba hahafahan’ny sosona ambony sy ambany mifandray, toy ny amin’ny alàlan’ny lavaka, ny lavaka voalohany, sns.

Ny lavaka fandavahana roa dia tsy mila milentika lavaka varahina, toy ny loaka visy, lavaka fametrahana, fantsohana hafanana sns., Ireo lavaka ireo dia tsy mila manana paosy varahina. Ny fandavahana faharoa dia tsy maintsy ao ambadiky ny voalohany, izany hoe misaraka ny fizotrany.

Olana mahazatra amin’ny fandavahana PCB

1. Fialana volo

Causes are: excessive spindle deflection; Fiasa tsy mety amin’ny milina fandavahana NC; Ny fisafidianana ny baomba dia tsy mety; Ny hafainganam-pandehan’ny kely dia tsy ampy ary ny tahan’ny fahana dia lehibe loatra. Be loatra ny fametahana sosona; Misy sundries eo anelanelan’ny tabilao sy ny tabilao na eo ambanin’ny takelaka fisaronana; Rehefa atsofoka ny halalin’ny vodin-tsambo dia lalina loatra ka miteraka fantsom-bitsika fantsom-pandavahana mihantona ratsy; Too many grinding times of the drill nozzle or beyond the service life; Voasarona sy ketrona ny takelaka manarona, ary miondrika sy tsy milamina ilay vilia tohana; When fixing the substrate, the tape is too wide or the aluminum sheet and plate of the cover plate are too small; Haingam-pandeha ny famahanana haingana ka mahatonga ny fihoaram-pefy; Improper operation when filling holes; Serious ash blocking under aluminum plate of cover plate; Ny afovoan’ny tendrony fandavahana welding dia miala amin’ny afovoan’ny fametahana boribory.

2. Hole damage

Ireto ny antony: toy izao ny fakana ny vilan’ny fandavahana aorian’ny fanapahana ny vilan’ny fandavahana; No aluminum sheet or clamping back plate when drilling; Parameter error; Elongated ny fandavahana; Ny halavan’ny bokotra fandavahana dia tsy afaka mihaona amin’ny hatevin’ny takelaka fandavahana. Hand drilling; Takelaka manokana, atolotry ny batch no nahatonga izany.

3. Fiviliana amin’ny lavaka, fanovana, fanitsiana

Ireto ny antony: toy izao ny fihenan’ny borosy mandritra ny fandavahana; Improper selection of cover material, soft and hard discomfort; Base material to produce shrinkage caused by hole deviation; Fampiasana tsy mety ny fitaovana fampifandraisana mifanaraka; Rehefa atsofoka tsy mety ny tongotra fanerena, kitiho ny pin mba hampandehanana ny lovia famokarana; Resonance occurs during drill operation; Spring collet is not clean or damaged; Famokarana takelaka, lavaka offset tontonana na offset stack manontolo; The drill bit slides when running the contact cover plate. Scratches or creases on the surface of aluminum sheet of cover plate produce deviation when guiding the drill nozzle to drill down; Tsy misy tsimatra; Different origin; Ny taratasy adhesive dia tsy mifatotra mafy; The X and Y axes of the drilling machine have movement deviation; There is a problem with the program.

4. Big hole, small hole, aperture distortion

Ny antony dia: lesoka famaritana nozoro; Hafainganana famahanana diso na hafainganana fihodinana; Fampiasana tendron’ny fandavahana be loatra; Too many times of regrinding of the drill nozzle or the bottom length of chip removing groove is lower than the standard; Ny fiviliana be loatra amin’ny spindle tenany; Nianjera ny tendrony fandavahana, ary nanjary lehibe kokoa ny savaivon’ny lavaka; Diso famakiana ny vavahady; Ny refin’ny savaivony dia tsy refesina rehefa novaina ny tendrony fandavahana; Drill bit alignment error; Ampidiro ny toerana tsy mety rehefa manova ny tsimoka fandavahana; Ny tabilao aperture dia tsy voamarina; Ny spindle dia tsy afaka mametraka antsy, ka miteraka tsindry fanindriana; Parameter entered wrong serial number.

5. Fitrandrahana am-pivoahana

The reasons are as follows: drill break (unclear mark); Pause midway; Hadisoana amin’ny programa; Unintentionally delete the program; Tsy nahomby tamin’ny famakiana angon-drakitra ny rig.

6. Front

The causes are as follows: Parameter error; Drill nozzle wear serious, blade is not sharp; Tsy ampy ny haavon’ny gorodona; There are sundries between substrate and substrate, substrate and bottom plate; Miondrika ny takelaka ifotony mba hamorona banga; Tsy misy takelaka fonony; The plate material is special.

7. Ny lavaka dia tsy nolavahana (tsy tamin’ny alàlan’ny substrate)

The reasons are: improper depth; The length of the drill is not enough; Sehatra tsy mitovy; Uneven thickness of the backing plate; Broken knife or drill nozzle broken half, the hole is not through; Ampidiro ao anaty lavaka ny banga aorian’ny fametahana varahina vita amin’ny koka; Spindle clamp malalaka, amin’ny dingan’ny fandavahana ny baomba dia tsindry fohy; No clamping bottom plate; Rehefa manao ny takelaka voalohany na ny famenoana lavaka dia nasiana pads roa izay tsy novaina nandritra ny famokarana.

There is a lotus-tied curling chip on the face plate

Ny antony dia: tsy misy takelaka fonosana na fisafidianana tsy mety ireo masontsivana momba ny fandavahana.

9. Lavaka plug (lavaka plug)

Ny antony dia ireto manaraka ireto: ny halavan’ny boriborintany mahomby dia tsy ampy; The depth of the drill into the backing plate is too deep; Olana ara-pitaovana (rano sy loto); Ampiasao indray ny takelaka; Noho ny fepetra fanodinana tsy mety, toy ny herinaratra banga tsy ampy; Tsy tsara ny firafitry ny baomba fandavahana; The feed speed of the drill tip is too fast and the rise is improper.

10. rindrina loaka henjana

Ny antony dia ireto manaraka ireto: miova be loatra ny habetsahan’ny sakafo; Haingana loatra ny tahan’ny famahanana; Improper selection of cover material; Fixed bit vacuum degree insufficient (air pressure); Ny tahan’ny fihenam-bidy dia tsy mety; The cutting edge of the tip Angle of the bit is broken or damaged; Goavana loatra ny fiviliana spindle; Fampisehoana famoahana puce ratsy

11. Ny faribolana fotsy dia miseho eo amin’ny sisin’ny lavaka (ny sosona varahina eo an-tsisin’ny lavaka dia misaraka amin’ny fitaovana fototra ary mipoaka ny lavaka)

Antony: ny fitrandrahana dia miteraka fihenjanana amin’ny hafanana sy hery mekanika ateraky ny fahatapahana eo an-toerana ny vongan-tany; Ny lamba fitaratra vita amin’ny kofehy vita amin’ny kofehy dia masiaka; Ratsy kalitaon’ny fitaovana substrate (ravin-taratasy); Be loatra ny habetsahan’ny sakafo; Malalaka sy malama malama ary raikitra ny vainga fandavahana; Too many stacking layers.

Ny etsy ambony dia matetika no olana amin’ny famokarana fitrandrahana, amin’ny tena fandidiana dia tokony ho fandrefesana bebe kokoa sy fanaraha-maso bebe kokoa. Mandritra izany fotoana izany, ny fandidiana henjana henjana dia misy tombony lehibe hifehezana ny tsy fahombiazan’ny kalitaon’ny famokarana, hanatsarana ny kalitaon’ny vokatra, hanatsarana ny fahombiazan’ny famokarana, koa dia manana fanampiana lehibe.
