TRS Advanced Maintenance

Objective 1: Locate the hazardous areas of the machine.

Warning

* Moving machine parts can cause injury.

* During this course the machine may be operated with covers

removed.

* Always remove system power prior to undertaking any work on

machine.

* Ensure you DO NOT push or press any buttons or operate the

machine until all personnel are clear of danger.

Personal Safety

Tick each safety item as it is demonstrated to you by your instructor:

Strong Magnet Warning (Machines with Linear Motors only)

The linear motors inside the machine contain*

strong permanent magnets.

These may interfere with pacemakers and metallic implants.*

These magnets could potentially erase data on credit cards,*

ID cards etc.

))

((

Wear eye protection and gloves when working with solder paste

and solvents.

If in doubt press the E-stop, EMO

Do not bypass camsafe switches

ESD Hazard

* The printer contains Electro-Static Sensitive Devices (ESD).

* Do not touch any electronic component of PCB unless wearing

a correctly grounded wrist strap.

Safety Objective

I have been briefed on the above safety aspects and I am fully satised with my

responsibilities..

Objective 2: Identify the key benefits and features of the TRS option.

• Ball placement application on singulated substrates (BGA devices) improved by Z

locking towers

• Better print quality with improve co-planarity (TRP improvements)

• Better alignment capabilities through less tolerance stack up (active surround system)

• JEDEC tray, J boat, Flat boat

• Passive solder paste printing down to 01005

• Processing singulated substrates typically PGA, LGA flip chip devices for GPU or

CPU’s

• Processing multiple substrates from carriers in a single process stroke

• TRP (Top referencing plate) a structure that compresses the substrates removing

warpage

• Active surround for substrate alignment and snugging

• Z locking towers for substrate thickness variation

• Self-centring towers, with no alignment capabilities for improved throughput a low

carrier interference
