F-E2B UV STENCIL

F-E2B UV STENCIL

Product Breakdown

This product is a “UV stencil,” which indicates a specific and advanced use in micro-soldering. Here is a detailed description:

• UV Stencil: Unlike a traditional reballing stencil used for applying solder balls, a UV stencil is designed for solder mask repair. The “UV” part of the name signifies that it’s used with a UV-curable solder mask oil (often called “green oil”). The process involves:
  1. Cleaning the damaged area on a circuit board where a pad has lifted or the protective solder mask has peeled off.
  2. Placing the UV stencil over the area to precisely align with the remaining pads.
  3. Applying the liquid solder mask through the stencil’s apertures.
  4. Curing the solder mask with a UV light for a short period (typically 6-15 seconds) to create a new, hard, insulating layer.
• F-E2B: This is the specific model or code for the stencil. It is part of a series of stencils from professional tool manufacturers like AMAOE or JTX. The “E2B” likely refers to a specific chip series or a group of related components, such as a eMMC (embedded Multi-Media Card), NAND flash memory, or a power management IC, commonly found in a wide variety of mobile devices and other electronics.

Purpose and Application

This tool is a crucial part of a professional technician’s kit for high-level electronic repair. It is not used for a simple reballing process but for a more complex and delicate step that comes before reballing.

• Core Function: The stencil’s primary purpose is to repair damaged solder pads on a PCB. Without a proper solder mask, a new chip cannot be successfully reballed and installed. The UV stencil ensures the new pads are perfectly shaped and insulated, preventing short circuits and ensuring a reliable connection.

   

• Why a Technician Needs It: It is used in complex repair scenarios where a simple reballing is not enough. The UV stencil provides the precision necessary to repair micro-scale damage that would otherwise make a motherboard or component unusable.
• Target Audience: This product is intended for skilled micro-soldering professionals who have the necessary equipment, such as a microscope, a UV lamp, and UV-curable solder mask.

FEATURES:

SOLDER MASK REPAIR GREEN OIL UV STENCIL

EACH STENCIL IS PROOFREAD ACCORDING TO THE ORIGINAL FACTORY DRAWINGS TO

ENSURE THAT EVERY SOLDER JOINT MUST NOT BE MISSING, COMPLETELY CONSISTENT WITH PRECISE ALIGNMENT

HIGH PRECISION, NO BURRS, SO THAT EACH OF YOUR MESH HOLES CAN BE OF THE SAME SIZE AND NOT STUCK TIN BALLS

HOW TO USE:

AFTER CLEANING THE MOTHERBOARD OR CHIP PART, DRY IT WITH AN AIR GUN TO KEEP IT DRY

USE A BLADE TO APPLY AN APPROPRIATE AMOUNT OF CURING GREEN OIL PARALLEL TO THE CHIP OR MOTHERBOARD THAT NEEDS TO BE REPAIRED

PAY ATTENTION TO APPLYING THE GREEN OIL AS EVENLY AS POSSIBLE, THE THINNER THE COATING, THE BETTER, TRY NOT TO HAVE AIR BUBBLES WHEN LAMINATING

THEN PUT THE GREEN OIL STENCIL (THE PRINTED SIDE) DOWN AGAINST THE PADS, AND THE PADS ON THE GREEN OIL NET ARE ALIGNED WITH THE PADS ON THE CHIP OR THE MOTHERBOARD.

ACCORDING TO THE THICKNESS OF THE APPLIED GREEN OIL, IT IS CURED BY THE PURPLE LIGHT EMITTED BY THE PURPLE LIGHT LAMP FOR 6-15 SECONDS

CLEAN THE PAD PART WITH PCB WATER OR ALCOHOL, AND THEN CONTINUE TO USE THE CURING LAMP TO CURE IT FIRMLY, THAT IS, COMPLETE THE QUICK REPAIR OF THE CHIP OR MOTHERBOARD PAINT DROP
