READ THE SAFETY AND APPLICATIONS INFORMATION SECTION IN THE OPERATION AND MAINTENANCE
MANUAL THOROUGHLY BEFORE INSTALLING AND USING YOUR NITROGEN FARM SYSTEM.

CAUTION

Use of this Manual

This manual will provide the user with the basic information to properly operate and maintain the PACE
NF 50 & NF 100 Nitrogen Farm. If you encounter any difficulty operating your system or have any
questions, call your local authorized PACE dealer or contact PACE Applications Engineering directly at the
United Kingdom Office on: Tel. [phone], Fax [phone], or PACE Technical Support at
the U.S. Office on: Tel: [phone], Fax [phone].

The compact, high performance single station N² generator (NF 100) will generate Nitrogen Gas at a
maximum concentration level of 99.9%. This system should be used in conjunction with NF 50 N² Flow
Control Unit. The NF 50 & NF 100 represents the latest technology in affordable Nitrogen Generation.

FAILURE TO COMPLY WITH THE APPLICATION AND MAINTENANCE GUIDELINES, FILTER REPLACEMENT
SCHEDULES, MONITORING RECOMMENDATIONS AND SAFETY GUIDELINES CONTAINED HEREIN AND
IN OTHER RELEVANT PRODUCT SAFETY LITERATURE (I.E., MATERIALS SAFETY DATA SHEETS) PROVIDED
WITH THE SUBSTANCES AND EQUIPMENT COULD RESULT IN RISK OF SERIOUS INJURY, FIRE OR
EXPLOSION.

Introduction

Lead Free solders do not behave or look like their lead containing counterparts. As our industry changes
over to Lead Free solders, individual PCB assemblers will need to address several issues relating to hand
soldering & rework. These issues include:

• Higher melting temperatures - which mistakenly lead to operators increasing equipment

operating temperatures. Higher operating temperatures do not make the process quicker; they
can actually slow it down.

• Poor wetting and spreading properties — Additional time is required when working with Lead

Free solders, they do not spread or wet like lead containing solders do. Operators must slow
down.

• Difficult to work with — Bridging and insufficient solder defects are common, even for

experienced operators, leading to operator frustration and poor quality.

• Dull grainy finish — makes inspection difficult.

The use of nitrogen assisted soldering equipment helps to mitigate the problems associated with using
Lead Free solders. Nitrogen helps on two fronts. First, it creates an inert environment around the
soldering tip, reducing the potential for the tip to oxidize. Second, it assists in the soldering process at
the PCB level by purging oxygen from the immediate area which reduces or eliminates the formation of
oxidation on the work site. This not only reduces the amount of flux that is required, but also helps to
improve wetting, spreading and leaves a finish that is shinier and less grainy.

PACE’s nitrogen assisted soldering systems pass the nitrogen through or around the heater before it is
directed to the work site. This “pre-heats” the immediate area which can also help to reduce thermal
shock to the component leads and to components themselves. Pre-heating also allows for the use of
lower, safer and more effective soldering temperatures.

The compact high-performance Single Station N² Generator (NF 100) will generate nitrogen gas at a
maximum concentration level of 99.9%. The NF 100 should be used in conjunction with the NF 50 N²
Flow Control Unit.
