FAQ of the semi-auto optical bga reballing machine

1. Q: what is a BGA rework station?

A: a hot air/IR station is used to heat devices and melt solder, and specialised tools are used to pick up and position often tiny components.

2.Q: What temperature do you need to Desolder?

A: Usually , the lead solder ball to be desoldered, the temperature can be set a lower, if lead-free solder ball , the temperature needs to be set higher , but Remember if the temp is too low to melt the solder,it can be set not more than 400C° If yos till struggle with it, just add some of solder to the mounted components, then works.

3.Q: What is the “BGA”?

A:ball grid array(BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors.

4. Q:What is the best temperature in soldering?

A:The melting point of most solder is in the region of 188°C (370°F) and the hot air temperature is set 160°C to 280°C (320°F to 536°F). usually, temperature should always start at the lowest temperature possible.

PROCEDURE 

1.Clean the area.

2.Drill into delamination blister with the Micro-Drill and ball mill. Drill in an area clear of circuitry or components. Drill at least two holes opposite each other around the perimeter of the delamination. (See Figure 1). Brush away all loose material.

CAUTION

Be careful not to drill too deep exposing internal circuits or planes.

CAUTION

Abrasion operations can generate electrostatic charges.

3. Bake the PC board to remove any entrapped moisture. Do not allow the PC board to cool prior to injecting the epoxy.

CAUTION

Some components may be sensitive to high temperature.

4.Mix the epoxy. See manufacturers instructions on how to mix epoxy without bubbles.

CAUTION

Exercise care to prevent bubbles in the epoxy mixture.

5. Pour the epoxy into the epoxy cartridge.

6. Inject the epoxy into one of the holes in the delamination. (See Figure 2). The heat retained in the PC board will improve the flow characteristics of the epoxy and will draw the epoxy into the void

area filling it completely.

7. If the void does not fill completely, the following procedures may be

used:

A. Apply light local pressure on the board surface starting at the fill hole, slowly proceeding to the vent hole.

B. Apply vacuum to the vent hole to draw the epoxy through the void.

8. Cure the epoxy per Procedure 2.7 Epoxy Mixing and Handling.

9. Scrape away any excess epoxy using the Precision Knife or Scraper.
