How to Solder

2009-08-24T03:02:00.000-07:00

Soldering is an integral and important of any electronics PCB manufacturing, assembly and rework / repair./ Soldering is defined as "the joining of metals by a fusion of alloys which have relatively low melting points e.g. alloy of tin and lead (sn/pb)". This allows is called solder, which could be solder wire, solder bar, solder paste, solder balls or solder preforms. Kester is the leading manufacturers and suppliers of solder and solder materials. In electronics industry, soldering is done to mainly to solder electronic components on to the circuit board to get a circuit board assembly.

Soldering of Surface Mount Components

2009-08-12T01:17:00.001-07:00

There are many soldering process available for surface mount components but none is perfect for all applications. All SMD soldering processes have technical concerns and there are ways to resolve those concerns. Because it offers higher yield and lower operation cost, convection dominant IR soldering has evolved as the preferred process for reflow soldering.

The selection of a soldering process depends on the mix of electronic components to be soldered. Various soldering processes will complement each other instead of replacing them. Even hand soldering is not going to disappear entirely.

Soldering Metallurgy

2009-08-11T13:50:00.000-07:00

The metallurgy of soldering is the key to understanding the mechanisms of intermetallic formation and solderability testing. A basic knowledge of phase diagrams of the metals used in soldering permits one to determine the solubility of one metal in another. The solubility controls important variables such as alloy composition, melting point for soldering, and occurrence of leaching.

Calibration of Weller Soldering Stations (Model(s): WSD81 / WSD161 / WSL / WSL2)

2009-01-28T08:38:00.002-08:00

Weller Soldering Stations / Systems are designed and manufactured to strict quality specifications and do not require calibration due to the use of Microprocessor Temperature Control and the use of precision Platinum (RTD – Resistance Temperature Detector) Sensors. Unlike conventional technologies which required the use of potentiometers (pots) to make adjustments to the control parameters for analog circuitry, the Weller WSD and WSL series of soldering systems provide the use of stored microprocessor control parameters that do not
require adjustments for calibration.

Weller WSD and WSL soldering stations / systems meet the Temperature Stability Requirements for MILSTD- 2000A (± 10° F / ± 6° C) and IPC/EIA J-STD-001C – Appendix A (± 9° F/ ± 5° C) of the idle tip temperature. These requirements address the capability of the soldering system to control the stability of the soldering irons tip temperature under an idle condition.

Weller also provides an individual manufacturer’s specification for Temperature Accuracy. An accuracy tolerance of ± 2% of the station setting (850° F Maximum Setting = ± 17° F). Additionally, for the convenience of customers who may demand an even greater Accuracy requirement, Weller offers a Tip Temperature “Offset” Feature that allows the individual customer the capability of “fine tuning” the actual tip temperature to a much closer tolerance.
The “Offset” Feature can be performed with the optional WCB1 Control Module. The “Offset” Feature is not a requirement for calibration, but is instead an avenue for providing a greater means of accuracy, if desired. If an “Offset” is input into a Weller Soldering System, the WCB1 Control Module may also be used to revert back to the Factory Default Values by initiating the factory “CAL” Key. At this time, the factory default parameters will be restored.

Note: Tip Temperature Accuracy depends greatly on the method of measurement used. Weller recommends the use of the Weller Model WA2000 Soldering Tool Analyzer for temperature accuracy or stability. Weller also recommends the use of a calibration tip assembly with a welded thermocouple for the highest degree of accuracy.

Weller: Lead Free (RoHS / WEEE) and Weller?

2009-01-28T08:38:00.001-08:00

The electronics industry around the world is moving to Lead Free (enforcement date of July 1, 2006) to meet the European Union’s WEEE (Waste Electrical and Electronic Equipment) and the RoHS (Restriction on Hazardous Substances) regulations.Original Equipment Manufacturers (OEM’s) around the world and Electronic Manufacturing Services (EMS) companies are preparing for Lead-Free circuit board assemblies. The recommendation for the industry to adopt a maximum allowable percentage of 0.1 % by weight of Lead in “Lead Free” products is fast approaching. Due to the drive to reduce the overall amount of Lead in manufacturer’s products, changes are very rapidly occurring worldwide.

Weller is committed to leading the environmental challenges of the future by complying with the European Union’s WEEE and RoHS directive to ban hazardous materials. Weller, a Division of Cooper Hand Tools, is determined to play a significant role in the leadership of this challenge.
Advances in Technology of LeadFree Solders and lead-free soldering.

As new Lead Free solder alloys emerge in the marketplace, soldering equipment must also change to meet the growing needs of increased temperatures of lead-free solder for the higher melting point alloys. Weller’s more recent advancement in the Silver Series technology of high wattage (65 to 80 Watt) soldering equipment, are prepared to handle these challenges developed by lead-free.

Solders produced from high percentages of Tin (Sn); accompanied by small percentages of Silver (Ag), Copper (Cu) (SAC) and occasionally Bismuth (Bi) are the leading candidates for new alloys for lead-free solder in the electronics industry. Standard alloys of Sn 96.5/Ag 3.5 and Sn 96.5/Ag 3.0/Cu 0.5 (SAC) are being chosen as the closest overall replacements for Eutectic (Sn63 / Pb 37).

Along with an increase in the melting points of the new alloys, advancements in the way that hand soldering tools perform are critical as well. The requirement to transfer heat to the application without significantly increasing the working temperature of the soldering tool being used can only be achieved by increasing the thermal capacity of the tool. This is very well achieved by NEW Soldering Stations and Soldering irons suitable for lead-free soldering from Weller.

Due to the nature of the higher Tin (Sn) content of the Lead Free alloys, advancements in soldering iron tip technologies also must change. New Soldering Tips from Weller is all prepared to face this challenge of lead-free.

PCB - Printed Circuit Board (Indepth Technical Update on PCB / PWB)

2009-01-12T02:17:00.000-08:00

A Printed Circuit Board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, or traces, etched from copper sheets laminated into a non-conductive substrate. It is also referred to as Printed Wiring Board (PWB) or etched wiring board.PCBs are rugged, inexpensive and can be highly reliable. They require much more layout efforts and higher initial cost that either wire-wrapped or point-to-point constructed circuits, but are much cheaper and faster for high-volume production. Much of the electronics industry’s PCB design, assembly, and quality control needs are set by standards that are published by IPC organization.

After the printed circuit board (PCB) is completed, electronic components must be attached to form a functional printed circuit assembly or PCA (sometimes called a “Printed circuit board assembly” PCBA). In through-hole construction, component leads are inserted in the holes. In surface-mount construction, the components are placed on the pads or lands on the outer surfaces of the PCB. In both kinds of construction, components leads are electrically and mechanically fixed to the board with a molten metal solder.

There are a variety of soldering techniques used to attach components to a PCB. High volume production is usually done with machine placement and bulk wave soldering or reflow ovens, but skilled technicians are able to solder very tiny parts ( e.g. 0202 packages which are 0.02” by 0.01”) by hand under microscope, using tweezers and fine tip soldering iron for small volume prototypes. Some parts are impossible to solder by hand, such as ball grid array (BGA) packages. Often, through-hole and surface-mount assembly must be combined in a single PCA because some required components are available only in surface-mount packages, while others are available only in through-hole packages. Another reason to use both methods is that through-hole mounting can provide needed strength for components likely to endure physical stress, while components that are expected to go untouched will take up less space using surface-mount techniques.

After the PCB has been assembled with electronic components, it may be tested in a variety of ways: - While the power is off, visual inspection, automated optical inspection can be done. JEDEC guidelines for PCB component placement, soldering, and inspection are commonly used to maintain quality control in this stage of PCB manufacturing.

- While the power is off, analog signature analysis, poweoff testing can be done.
- While the power is on, in-circuit tests, where physical measurements (i.e. voltage, frequency) can be done.
- While the power is on, functional test can be done to check if the PCB does what it had been designed for.

To facilitate these tests, PCBs may be designed with extra pads to make temporary connections. Sometimes these pads must be isolated with resistors. The in-circuit test may also exercise boundary scan test feature of some components. In-circuit test systems may also be used to program non-volatile memory components on the board.In boundary scan testing, test circuits integrate various ICs on the board form temporary connections between the PCB traces to test that the ICs are mounted correctly. Boundary scan testing requires that all the ICs to be tested use a standard test configuration procedure, the most common one being the Joint Test Action Group (JTAG) standard.

When boards fail the test, technicians may desolder and replace failed components. This is known a “PCB Rework”.

Some PCBs have trace layers inside the PCB and are called multi-layer PCBs. These are formed by bonding together separately etched thin boards. The primary intent of fabricating a multilayer printed circuit board is to provide one more degree of free in the selection of suitable routing paths for complex and/or noise sensitive electronic circuits. Such considerations as layer to layer impedance aside, what we are really trying to do is stack two or more circuits on top of one another and establish a reliable set of predetermined interconnections between them. There are a number of well established techniques that are routinely used by the PCB industry to accomplish this. However, they all suffer from their reliance on a large number of chemical processes to condition the substrate, activate the through-holes and electrolyticly plate copper between the adjacent layers. The following method reduces this dependence on “wet chemistry” to a single acid copper electroplating bath and relies on a small set of easily mastered processes to eliminate the need for much of the complexity normally encountered in multilayer board prototyping.The technique begins with the departure from conventional processing where all of the layers are drilled and plated before they are laminated together. The two innermost layers will comprise a conventional two-sided PCB and the various outer layers will be fabricated as separate single sided PCBs. Prior to lamination, the inner layer board will be drilled, plated through imaged, developed and etched. The drilled outer layers will be plated through in such a way that uniform donuts of ductile copper are formed on the underside rims of the thru-hole (remember that the underside is the side without the copper foil). During lamination of the various layers into a composite multilayer, these donuts bite into pads on the surface of the opposing layer of the PCB (Printed Circuit Board / PWB) to form gas-tight wave solderable interconnections.
