What happens if I use thinner encapsulant?

When using thinner encapsulant, you can save some cost however this can have severe impact on module’s reliability. A thinner encapsulant may not be able to withstand constant environment stresses that a module undergoes in field. Also, it might be unable to provide sufficient electrical protection properties, leading to lower than expected performance.

Brij recommends using EVA of 0.45mm thickness.

What are the standard available widths of encapsulant?

Brij stocks a variety of sizes of EVA in its warehouse for ready dispatch. Since this depends on the market requirements, it is best to contact us to know the sizes and stocks.

What widths can Brij manufacturer?

In our state of the art manufacturing facility, we can manufacturer widths upto 1300mm.

We maintain ready stock of widths 670mm, 680mm, 990mm and 1000mm at all times.

What is the indicative turn around time for dispatch?

For standard widths, generally goods can be dispatched within 72 hours from our warehouse. For non standard or special requirements, dispatch can be made within 10 days.

However it is important to confirm delivery terms at the time of purchase.

Low Adhesion

Why. It might be due to

Inappropriate curing parameters
Non uniform curing
Expired EVA/Improper Storage
Unclean glass or other materials

Solutions. The following solutions are recommended

Different EVA manufacturers have different parameters. Make sure the parameters are configured appropriately for Brij EVA. Improper curing will lead to incomplete crosslinking and hence less adhesion.
Ensure that curing is complete throughout the module. A deviation in properties of upto 30% can occur at different points on the laminate. This is generally due to the time difference between the center and the corners in reaching optimum curing temperature.
It is recommended to have a dust free laminating conditions to prevent contamination of the laminate with dust particles.
Ensure that the EVA is not expired and sealed & stored in its original packaging.

Bubble Formations

Why. It might be due to a variety of reasons like

Insufficient Vacuum/Sealed air in EVA
Unclean glass or other materials
Expired Product/Improper storage

Solutions. Following solutions are recommended

It may help to extend vacuum time and pressure & ensure that the laminating chamber is properly sealed. Also check the vacuum pump pumping rate to ensure that air is sucked completely before melting of EVA.
It is recommended to have a dust free laminating conditions to prevent contamination of the laminate with dust particles.
Ensure that the EVA is not expired and sealed & stored in its original packaging
