Do you know the principle of air bubble remover machine? Various industries use different kinds of bubble removers and the principle is different. Most people understand the principle is high pressure work, through the air compressor to the bubble remover pressurization. Although the high pressure will be the screen in the bubble squeeze out, but the LCD screen bubble remover principle is not the case. The air bubble remover machine works by having to pressurize the cylinder of the bubble remover through the air compressor, but not by squeezing out the air bubbles within the mobile screen through the high pressure. Nonetheless, the high pressure within the bubble remover is how to squeeze the air bubbles out of the screen. As a matter of fact, the high pressure work of the bubble removal equipment is not to squeeze out the bubbles in the screen, but through the high pressure of the screen bubbles and OCA adhesive to accomplish fusion, so that the bubbles disappear in the screen.
Maybe you will have questions. If the OCA adhesive and the bubble is the bad quality of the OCA adhesive, the inferior quality of the adhesive, the more impurities will be there, will cause the bubble rebound or bubble along with the bubble, hence try to select the OCA adhesive of superior quality to make sure the impact of bubble removal just like a screen refurbishing machine. Preheating station equipments can fetch the ideal uniform temperature profile that your application needs. We hope this post has bettered your idea why pre-heating station are a vital aspect of PCB assembly. Lessening thermal stress, activating the flux and lessening exposure to molten solder are just some of the advantages that these devices can bring to you. Hence, investing in a pre-heating station will always bring value to the assembly process.
