Loni, jẹ ki a ṣawari bi o ṣe le ṣe idanwo awọn stencil SMT. Ayẹwo didara ti awọn awoṣe stencil SMT jẹ pin ni akọkọ si awọn igbesẹ mẹrin wọnyi

Loni a yoo tẹsiwaju lati kọ ẹkọ nipa ọna ikẹhin ti iṣelọpọ PCB SMT stencil: Ilana arabara.

Loni a yoo tẹsiwaju lati kọ ẹkọ nipa ọna kẹta ti iṣelọpọ PCB SMT stencil: Electroforming.

Loni a yoo tẹsiwaju lati kọ ẹkọ nipa ọna keji ti iṣelọpọ PCB SMT stencils: Ige Laser. Ige lesa lọwọlọwọ jẹ ọna olokiki julọ fun iṣelọpọ awọn stencil SMT. Ninu ile-iṣẹ gbigbe-ati-ibi SMT, diẹ sii ju 95% ti awọn aṣelọpọ, pẹlu wa, lo gige laser fun iṣelọpọ stencil.

Loni, a yoo tẹsiwaju lati ṣawari awọn ọna mẹta ti iṣelọpọ PCB SMT stencils: Kemikali Etching (Chemical Etching Stencil), Laser Cutting (Laser Cutting Stencil), ati Electroforming (Electroformed Stencil). Jẹ ki a bẹrẹ ṣiṣe etching kemikali.

Loni, a yoo jiroro bi o ṣe le yan sisanra ati ṣe apẹrẹ awọn apertures nigba lilo awọn stencil SMT.

Loni a yoo kọ ẹkọ nipa diẹ ninu awọn paati PCB SMT pataki ati Awọn ibeere fun apẹrẹ ati iwọn ti awọn iho lori stencil titẹ sita lẹ pọ.

Jẹ ki a tẹsiwaju lati kọ ẹkọ nipa awọn ibeere apẹrẹ fun iṣelọpọ ti awọn stencil SMT. Ile-iṣẹ gbogbogbo le gba awọn oriṣi mẹta wọnyi ti awọn ọna kika iwe fun ṣiṣe stencil Ni afikun, awọn ohun elo ti a nilo lati ọdọ awọn alabara fun ṣiṣe awọn awoṣe ni gbogbogbo pẹlu awọn ipele atẹle Apẹrẹ iho ti stencil yẹ ki o gbero didasilẹ ti lẹẹ lẹẹ, eyiti o pinnu nipataki nipasẹ awọn ifosiwewe mẹta wọnyi

Bayi jẹ ki a kọ ẹkọ nipa awọn ibeere apẹrẹ fun iṣelọpọ ti awọn stencil SMT. 1. Gbogbogbo Ilana 2. Stencil (SMT awoṣe) awọn imọran apẹrẹ iho 3. Igbaradi iwe-aṣẹ ṣaaju apẹrẹ awoṣe stencil SMT

Sipesifikesonu ilana iṣelọpọ SMT pẹlu ọpọlọpọ awọn paati pataki ati awọn igbesẹ lati rii daju didara ati deede ti stencil. Bayi jẹ ki a kọ ẹkọ nipa awọn eroja pataki ti o ni ipa ninu iṣelọpọ ti awọn stencil SMT: 1. fireemu 2. Apapo 3. Stencil Dì 4. alemora 5. Ilana Ṣiṣe Stencil 6. Stencil Design 7. Stencil ẹdọfu 8.
