Consigned Assembly – Detailed Overview

To make modern Printed Circuit Board (PCB) is an art form with involvement of special skill and knowledge. The entire process requires extreme effort from auditing a consigned kit to make the ultimate final quality inspection. By use of the Consigned assembly you can bring your product to market on time.

Required Materials for Consigned Assembly:

Among the available Electronic assembly services, Consigned assembly is considered as an important one. The components that are needed are supplied by the customer. There are number of reasons that are considered for consignment of the materials – the product can be much expensive or it can also be proprietary product or the customer can also have a large inventory.

Kitting of Consigned Assembly:

An absolutely through audit is made for consigned kits as they reaches our dock. The Bill-of-Materials (BOM) can be compared to the components that are supplied and also verify the accuracy in values, part numbers, package types and sizes and also tolerances. The report of an audit is normally generated within forty eight hours.

There are a certain number of considerations that are to be taken into account:

·         Component Shortages – Mainly shortage of components is considered to be the most important reason for any delay of delivery. In most of the cases, the building of the circuit is not started unless every shortage issues are solved.

·         Special Handling— Requirement of any special handling, especially if solder reflow profiles are required or if there is any restrictions in the process of washing like washing in an aqueous cleaner is strictly restricted. Thus any such special handling if required then it must be informed.

Kits Supply

The components in your kit must be supplied either as continuous strips of tape or by proper packaging or with clearly labeled parts. Before the final release, the Kit Audit department must review carefully all the parts of your kit to ensure proper quantity and quality of the components.

Considering all the above information, Consigned assembly is treated as one of the finest program for PCB’s among the huge variations of Electronic assembly services that are available in the modern market.

PCB Assembly Services – A Brief Introduction

You might have heard of PCB assembly services, but might not have any idea about this term exactly. Let’s make things simple for you to understand.

The entire procedure of manufacturing electrical devices is quite complicated and even time consuming. Materials play an important part in electrical manufacturing. These include silicon or other semi-conductors. By following numerous expensive and long clean room procedures, wafers are successfully converted into electronic chips and microprocessors. These chips are unable to carry out any job on their own. They are required to be integrated into PCB for carrying out activities like operating the phone or the computer.

There are many companies that deal in designing such chips but all these companies do not have the capability of buying all the tools needed for assembling the chips on to the PCBs for devising end-products. This job is carried out by the PCB assembly companies. Such companies possess many Surface Mount Assembly lines with services in the field of assembling PCB.

PCB assembling and fabrication companies offer their services to various companies who do not have any interest in carrying out such activities themselves.

The PCB Fabrication Procedure

The PCB fabrication procedure consists of a large number of processes and they are as follows:

·     Printing Solder Paste: This is the procedure during which the initial solder paste is successfully  printed onto the printed circuit board by making use of a stencil.

·       Pick and Place Assembly of SMT: This serves as the heart of the PCB line. The procedure takes  different individual chips and places them accurately at the right positions on the circuit board.

·      Through-Hole or Reflow Curing: Post placing the different chips on the solder paste, the circuit  board goes through a kind of conveyor oven for melting the solder and binding the chips onto the    PCB.

 There are many other small steps carried out in fabricating a circuit board. Shax Engineering is one of the  specialist manufacturers of different types of assembly fields for printed circuit boards.

Steps To Bring Success in Concurrent Engineering

In today’s market of cut-throat competition, there has been a creation of intensive demand on the company’s management team of project managers and engineers to deliver economic, faster and flawless products within the stipulated time frame. 

The main objective of a designer is to structure a functioning product within the available schedule and economic restraints. But with the rising technological development and reduced timeframe, there area growing number of jobless staffs in the market. Here, concurrent engineering comes as a help, as concurrent engineering allows early consideration of manufacturing and designing aspects giving scope to the designers to optimize product quality, manufacturability, serviceability,flexibility, cost, market acceptance and timely delivery.

Some Basic Principles of Concurrent Engineering:

• To comprehend product requirement.

• Establish clear business mission and project goals.

• Integrate development process.

• Structure parts and suppliers at initial project stage.

• Implement software tools, integrate CAD,CAE, and CAM.

• Establish functional building blocks.

• Electronically simulate manufacturing processes and product performance.

• Implement quality and reliable Engineering techniques.

• Constantly review progress and revise plan.

Concurrent engineering involves the creation of an environment where a multi-functional team works in unity to optimize designs of Flexible circuit prototype, and its manufacturing process. The engineering team actively works together from a very initial stage through manufacturing, design, purchasing, finance in a very cooperative manner. The team with their combined effort produces a functionally active and optimized product to help reduce the manufacturing and development expense, improves product quality, simplify assembly process,bring down delivery time and enhance overall reliability and development providing an economical, strong and effective solution to meet current age challenges.

Shax Engineering is a company specialized in providing total solutions to PCB concept. The company offers high-quality PCB fabrication and PCB assembly services for quick-turn prototypes and NPI users.

Great Use of Flexible Circuit Prototype and Ways of Making the Design More Robust

Flexible circuit prototype offers a great opportunity for the packing of electronic designer and engineering designer. They are very versatile electronic wires and systems that may be bent, shaped, twisted or folded into the endless dimensional configuration. They are much better than the inflexible and rigid PCB or printed circuit boards. The added dimension makes the flex circuit a dream of engineering but adding some flexibility can make the entire design greatly flexible.

Various kinds of manufacturing techniques are used for flexible circuit prototype. When it is the rigid and printed circuit, it would be more stable dimensionally. There is standard polyimide film that is employed as the main component in about 95% of flex circuits. The increase in the dimensional variability implies that the flexible circuit needs various design rules. The rules are more when compared to printed circuit boards.

How to Make the Design More Flexible?

To make the design more ready for fabrication, producible and robust, you need to consider the following:

• During the making of the flexible circuitry or circuit board prototype, there can be dimensional change after an exposure to the processes like copper plating, pumice scrubbing and etching. When it comes to the design rules of flexible circuitry, larger tolerances are required. This accommodates the registrations for stiffeners, cover film and the die cutting. You need to be careful about it.

• There can be more solder spacing between the pads and also adjacent traces. This design compromise is the direct consequence of the first point or flaw.
