About this file
This is a Test & Inspection Plan (TIP) document for the AFE Enclosure, a component of the Advanced Light Source Upgrade (ALS-U) project at Lawrence Berkeley National Laboratory. Document number AL-1880-6554, Revision A, was released March 31, 2026.
The TIP establishes the test and inspection process for assembling and verifying the AFE (Analog Front End) enclosure, which consists of three circuit boards (AFE Board A, B, and C), one backside board, two lids, and the main enclosure housing. The procedure requires 24 socket head screws (1/8") for board installation and 29 socket head screws (1/4") for lid attachment, along with supporting tools including torque screwdrivers, nut drivers, and SMA fittings. The inspection process includes visual examination for surface defects (scratches, dents, rust, oxidation), verification of proper coating application, confirmation of correct labeling and part numbers (AL-1809-0328 for enclosure, AL-1809-0361 for lids), and validation of X and Y axis engravings. The fitment check verifies that all components install correctly and all screws can be easily secured without obstruction. Testing requires a verification signoff sheet capturing serial number, test dates, tester name, and completion sign-off by an entity independent of the assembly technician. All test steps must be documented with PASS/FAIL results and photographic evidence of installed boards.

1. Enter the following information on the Verification Signoff Sheet:
a. SERIAL NUMBER
b. START DATE
c. TIP NUMBER AND REVISION
d. TESTER(S) NAME
6.2 Inspection
6.2.1 Visual Inspection
1. Inspect for scratches, dents, deformations, rust, or oxidation.
2. Check that all sharp edges are removed.
3. Verify that the coating was properly applied. (i.e. There’s no flaking or patches)
4. Verify that the enclosure is labeled with the correct AL#. (AL-1809-0328, Rev_)
5. Verify the X and Y axis are engraved to the side of the AFE enclosure. (Figure 1)
6.2.2Fitment Check
1. Load AFE Board A, B, and C into the deeper side of the AFE enclosure. (Figure 2)
a. Use 1-72 socket head screws ⅛” and screwdriver to tighten down the three boards.
b. Verify all screws can be easily secured to the enclosure.
2. Load the AFE backside board on the shallow end of the AFE enclosure. (Figure 3)
a. Use 1-72 socket head screws ⅛” and screwdriver to tighten down the three boards.
b. Verify all screws can be easily secured to the enclosure.
3. Verify that the AFE Lids are labeled with correct AL#. (AL-1809-0361)
4. Attach the AFE Lid to the enclosure using 1-72 head screws ¼”.
