Soldering in Electronics – Hand Soldering | Automated Soldering | SMT Soldering | BGA Soldering | All Process of Soldering in Electronics

Soldering in electronics is all about joining electronic components to the PCB by hand using soldering station or soldering iron, or wave soldering using wave soldering machine or reflow soldering using reflow machine.  Soldering can be either hand soldering or automated soldering. It can also be either thru-hole soldering or SMT Soldering using Surface Mount …

Lead-Free (Pb-Free) Solder and Composition

Lead-Free Solder: Solder with NO Lead (Pb). Lead-Free is taking rapid momentum around the world after the EU (European Union) Directives to wipe off lead (Poison) from electronic soldering considering its health and environmental effects

RoHS: Restriction of Hazardous Substances [ lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE).]…

SMT Repair and Inspection Equipment

Equipment unique to surface mounting includes inspection and repair / rework equipment. Inspection equipment for surface mounting in electronics has not matured yet. There are two main types of automated inspection equipment on the market: x-ray and laser. However, most electronic companies depend on visual inspection at 2 to 10X, using either microscope of magnifying lamp.

Repair / Rework equipment …

SMT Curing / Baking Oven for SMT Soldering

There are three types of Surface Mounting: Type 1, Type II and Type III.

For Type III surface mount, components glued to the bottom of the board require curing before wave soldering. In addition, electronic components placed on the solder paste in Type I and Type II Surface Mount Technology assemblies achieve reduced solder defects (such as solder balls) by …

SMT Solder Paste Screen Printer Machine for Solder Paste Screen Printing

A Solder Paste Screen Printer for SMT is needed to screen solder paste onto the printed circuit board (PCB) before placement of surface mount components.

Solder Paste Screen Printer for SMT have been widely used in electronics by the PCB industry for screen solder mask. This equipment / machine has also been extensively used in the hybrid industry for screening …

Types of Surface Mounting in SMT

Many electronic components are not yet available in SMD for surface mounting. Due to this reason, SMT must accommodate some through-hole components. Therefore the term “Surface Mount Assembly is incomplete”. Surface mount components, active and passive, when attached to the substrate, form three major types of SMT assembly – commonly referred to as Type I, Type II and Type …

Basic Soldering Guide – How to Solder Electronic Components

Proper soldering technique and quality of solder are the lifeline of any PCB manufacturing and assembly. If you are into electronics, you must be knowing that soldering is basically a technique to join two metals using a third metal or alloy. In electronic PCB Manufacturing, assembly and rework, the metals to be joined are the leads of

RoHS Guide in Electronics: RoHS, WEEE and Lead-Free FAQ

If you are in Electronics Industry, Electronics Assembly and Manufacturing or Electronics Rework / repairing then you must have heard of RoHS, WEEE and Lead-Free.

  1. What is RoHS (Restriction of Hazardous Substances)?
  2. What is WEEE (Waste from Electrical and Electronic Equipment)?
  3. What is Lead-Free?

Let us discuss these in detail:

What is RoHS?

RoHS stands for Restriction of Hazardous Substances. …

BGA (Ball Grid Array): Repairing and Soldering BGA

Electronic Devices and Gadgets are getting smaller and slimmer day by day. All this is possible because of technological progress and development in electronics. Top Electronic Companies in the World are in competition to make the smallest and slimmest gadgets. SMDs or Surface Mount Devices and BGA or Ball Grid array are two electronic components responsible for making electronic devises …

Wave Soldering: Equipment & Process

Wave soldering is the most widely used method in electronics industry for soldering through-hole electronic components. Components glued to the bottom of a mixed-technology PCB require wave soldering, although the required wave geometry is different from that for through-hole electronic components. In the most common wave soldering geometry, the dual-wave type, one wave is turbulent and the other wave …

Soldering Station Guide

About Soldering Station

A soldering station is a soldering tool with a separate station to control temperature and a soldering iron. A soldering station can be either analog or digital.

A soldering station is an electronic tool for hand soldering of electronic components onto a PCB. It consists of a station or a unit to control temperature

How to Solder – Hand Soldering Tutorial

Hand soldering is done during PCB rework in a production unit when a PCB gets rejected or fails the quality pass test. Hand soldering is also done for repairing and servicing printed circuit boards by service centers.

The main focus of this article is to make you learn how to solder properly using the best hand soldering methods and techniques
