Many customers who have purchased the nitrogen cabinets have been in the mistaken belief that the air pipe can be pull down hard,so that it can cause the board to be damaged due to the hard pulling of the air pipe, which leads to the replacement of the penetrating board. Now, the following pictures are provided. Please note: Nitrogen cabinet is a optiomal choice for the microelectronics,semiconductor for humidity proof and anti-oxidation purpose,Climatest has put much efforts on the R&D of dry cabinets,as you know,our advangtage is to handle temperature and humidity,since early 1990s,our engineers began to test and research dry cabinet and nitrogen cabinet,all of our manufacturing process strictly follow ISO9001 standard,we supply to international customers for 20 years,if you are still looking for a reliable dry cabinet manufacturer to protect your MSD from moisture related damage,come to visit www.climatechambers.com,we are ready!

The change of squeegee pressure has a significant impact on printing. Too small pressure will make the solder paste unable to effectively reach the bottom of the stencil opening and not be well deposited on the pad. Too much pressure will cause tin The paste is printed too thin and can even damage the stencil.

Moisture trapped within components and PBs presents a serious problem during the fabrication and assembly process. Too much moisture can lead to board failures when it is turned to steam during the reflow process.

The performance of electronic components is compromised by factors such as bubbles in the potting medium. Increasing numbers of applications – particularly in the automotive and electronics industries – therefore require completely bubble-free dispensing methods. This is where potting in a vacuum comes into focus. The widespread school of thought about this technology is that it is too complicated, too expensive and too slow. But a closer look shows that this view is incorrect. This is a mastered technology. As for costs, the calculation basis is key, since usually the potting and vacuum method is only considered after the required potting quality cannot be achieved reliably any other way. Under total cost of ownership assessments, higher system costs no longer play a key role, since component failure would result in much higher subsequent costs. And now there are proven solutions for high production volumes and/or shorter cycle times. This whitepaper explains when potting in a vacuum is ideal for your projects and what to be aware of.
