Step 9: Test & Inspection

During the last 25 years, in-circuit test (ICT) has been the workhorse in finding manufacturing defects in assembled PCBs. Today, most PCBs have less than 100 percent probe access, challenging this proven test strategy. Higher densities, double-sided boards, advanced SMT packaging and higher frequencies are forcing engineers to remove test pads on many nets or nodes, limiting ICT effectiveness.

The liquid encapsulant can be applied manually or using an X-Y computer-driven automated dispense system. One of the fundamental advantages of the liquid encapsulation process is its simplicity and flexibility.

Account of a Cleaning Systems Changeover

Changes in cleaning methods at Raytheon's Electronic and Missile Systems products facility at Air Force Plant 44 in Tucson, Ariz. have resulted in improved environmental performance, more effective cleaning and substantial production cost reductions.

Lead-free Solder X-ray Inspection Implications

The most important consideration when X-raying a sample with lead-free solders is that radiation absorption increases with atomic number and density of the material present. Lead has a Z value (atomic number) of 82, compared with 50 for tin, 47 for silver and 29 for copper.

Flexible Circuit Market Trends

Flex circuits feature a three-dimensional shape, which saves a substantial amount of board space. The circuits also bend during installation and maintenance, making the rework and repair process easier.

Automated AMI Analysis of Components Prior to Board Assembly

Anomalies related to chip design, lithography or materials often are revealed by various types of electrical testing before assembly. Packaging-related failures, however, may be caused by a packaging anomaly that remains undetected until it leads to an electrical failure.

Reflow Profile Optimization

In surface mount assembly, a key step in producing finished assemblies is reflowing deposited solder paste. Solder paste commonly is reflowed in a convection IR oven, which heats the circuit board in stages. The time and temperature graph while the board is in the oven is referred to as the reflow profile.

New Geometries Drive Search for Flexible Manufacturing

Feature sizes in electronics assembly and packaging continue to decrease. Traces, spacings, bond pads and other geometries are a tenth the size they were a decade ago. Additionally, increasing production volumes must accommodate more frequent change orders, shorter marketing windows and materials flexibility.

Sanctions Against Sn/Pb Solder Paste

Solder paste using tin/lead, popularly known as Sn/Pb has been the most important element of solder paste until global agencies threatened its popularity in favor of lead-free solder paste and other environmentally friendly alternatives.


Step 8: Cleaning

Forces driving SMT cleaning are centered around cleaning product performance for the specific soil; air, water and solid waste environmental concerns; health and safety; residue left from low-residue soldering elevating end user reliability concerns; cost of ownership; and the conversion to lead-free alloys.
