With the rapid development of electronic products to light, thin, small, high-density, multi-functional and microelectronic integration technology, the volume of electronic components and printed circuit boards is also shrinking exponentially, and the assembly density is increasing.In order to adapt to this development trend, the predecessors developed the PCB plug technology, which effectively increased the PCB assembly density, reduced the product Volubilis, amplio stabilitatem et reliability specialis PCB products et promotus progressionem PCB products.
Sunt maxime tres genera metallum basi obturaculum foraminis technology, semi-solidatae sheet urgeat foraminis; Screen excudendi apparatus plug foraminis; Vacuum plug foraminis.
1.Semi-solidatae sheet urgeat foraminis
Est uti a semi-curatio sheet cum princeps contentus de glutine.
By means of vacuum hot pressing, the resin in the semi-curing sheet is filled into the hole that needs plug, while the position that does not need plug hole is protected by the protection material.After pressing, tear off the protective material, cut off the overflow glue, that is to get the plug hole plate finished product.
I). requiritur materiae et apparatu materiae, semi-curari sheet cum altum gluten contentus, tutela materiae (aluminium ffoyle, aeris ffoyle, dimittis film, etc), aeris ffoyle, dimittere amet
II). Equipment: CNC EXERCITATIO Machina, metallum substratum superficiem curatio linea, riveting apparatus, vacuo calidum torcular, balteus molere machina.
III). Technological processus: metallum substrati, tutela materiam secans → metallum substrati, tutela materiam EXERCITATIO → Metal Substratum Saturace Calor → Rivet → Laminate → Cut Nimia glutinum
2.Screen excudendi apparatus plug foraminis
refers to Ordinarius screen excudendi apparatus plug foraminis resina in foraminis in metallum substrati, et curing.after curing, interficiam off inundantiam, aut pistoria est, ut amisit per pluge foraminis et pistoria est, ita necesse est inhaero iacuit et in prematu et inhaeret, et exaltatam in tortor et inhaeret, aut in altum temperatus inhaero Terga ad suscipere resinae et terebro numerus caeli spiracula ad orificium locum faciliorem spiraculum plug foraminis.
I). Requiritur materiae et apparatu materiae, plug resina, summus temperatus defensiva amet, aer pulvinaribus laminam.
II) Equipment: CNC EXERCITATIO Machina, metallum substratum superficie curatio linea, screen excudendi apparatus, calidum aer clibano, balteus molere apparatus.
3) technological process: metal substrate, aluminum sheet cutting → metal substrate, aluminum sheet drilling → metal substrate surface treatment → stick high temperature protective film → drill air cushion plate drilling → screen printing machine plug hole → bake curing → tear high temperature protective film → cut excessive glue.
3.Vacuum plug foraminis
refers to the use of vacuum plug hole machine in a vacuum environment plug hole resin into the hole in the metal substrate, and then bake curing.After curing, cut off the overflow glue, that is, the plug hole plate finished products.Due to the relatively large diameter of the metal base plug hole plate (diameter of 1.5mm or more), the resin will be lost during the plug hole or baking process, so a Suspendisse caliditas tutela amet debet crustulum tergo ad suscipere resin ..
I). Requiritur materiae et apparatu materiae: plug resina, summus temperatus tutela amet.
II). Equipment: CNC terebro, metallum substratum superficiem curatio linea, vacuo obturaculum apparatus, calidum aer clibano, balteus TRITOR.
III) .Technological processus: metallum substrati aperire → metallum substratum, aluminium sheet tormentis → metallum substratum superficie curatio → crustulum et curatio → lacrimam → tormentis et curatio → lacrimam gluten.
Metal substrate main plug hole technology half a curing film pressure filling holes, silk-screen printing machine plug hole plug hole and vacuum machine, each plug hole technology has its advantages and disadvantages, should be in accordance with the requirements of product design, cost requirements, equipment types, such as a comprehensive screening, which can increase the production efficiency, improve product quality, reduce production cost.
