IPC's market report help you PCB project

Many PCB sales don’t know IPC. Jim don’t want to introduce this simple point. If you really don’t know IPC, please use google to search the definition of IPC.
IPC’s market research regularly unearths interesting findings that may reveal golden opportunities for electronics manufacturers. Here are some of the latest discoveries of interest to North American PCB fabricators:

Flexible PCB VS Rigid PCB

Flexible circuit orders in North America are booming this year and the forecast for the next year is for double-digit sales growth. The North American flex market has grown over the past 3 years while the rigid PCB market has shrunk. Globally, the flex market is now estimated at over $10.2 billion. Yet, U.S. production accounts for only 3.4 percent of the world’s flexible circuits.

HDI PCB VS microvia PCB

High-density interconnect (HDI) is another market that grew in double digits in 2014 and is growing even faster this year. HDI/microvia boards make up about 22 percent of the North American rigid PCB market. Yet the U.S. produces only 2.4 percent of the world’s microvia boards, and just 7 percent of the rigid PCBs produced in the U.S. are microvia boards.

Immersion Silver Surface Finish Comparer with ENIG and HASL

When you compare with ENIG or HASL PCB,Immersion Silver Surface Finish PCB is very new PCB type.
So we must introduce this very care full.And we will introduce several points about Immersion Silver PCB below:
-The difinition of Immersion Silver Plating PCB
-Immersion Silver Surface Finish Comparer with ENIG and HASL
-Hight performance of Immersion Silver Surface Finish
-The Packaging of Immersion Silver PCB

The difinition of Immersion Silver Plating PCB

Immersion Silver Plating is a surface plating technology used for Printed Circuit Boards,it is deposited directly on the copper surface by a chemical displacement reaction and is available in the industry all co-deposit and organic anti tarnish with the immersion silver. This reaction is fast and does not require the relatively high temperatures of ENIG

Immersion Silver Surface Finish Comparer with ENIG and HASL

Immersion Silver finish (also referred to as ‘IAg’), provides a ROHS compliant finish for printedcircuit boards (pcbs), but is thinner than ENIG or traditional HASL finish.

Hight performance of Immersion Silver Surface Finish

Immersion silver offers better performance and superior finishes for final
finishes on PCBs, and has been generally favored by clients.
That is the reason why more and more electronic company choose Immersion Silver PCB.

The Packaging of Immersion Silver PCB

Handling, packaging, and storage are the most challenge in the production of PCBs. It have to be more carefully when immersion silver are done. Packaging of immersion silver printed circuit boardis very important, it has to minimize contact of the surface with the environment and to ensure all materials used in the packaging and during storage are sulfur free.

What is Immersion Gold PCB?

Immersion Gold,also called ENIG, has been growing as one of the best finishing methods for printed circuit boards.
ENIG is a costlier finish, but offers the best characteristics for pcbs.

The Strengths of Immersion Gold PCB

Immersion gold chemistries offer many strengths like excellent surface planarity (particularly helpful for PCB’s with large BGA packages) coplanarity, excellent wettability, long shelf-life and surface oxidation.

The Advantage of the Immersion Gold PCB Surface Finish

ENIG doesn’t require frequent dummy plating, excellent re-flow cycles, and gives level plating around the shoulders of pads and circuits. Immersion gold finish also provides both good adhesion as well as providing outstanding electrical testability

Compare with Flash Gold Immersion PCB Surface Finish

Compared with flash gold Immersion gold finish is cheaper because the thickness of gold. However, with good solderability.

Lead Free PCB Also Require RoHS Compliance

RoHS compliance,which took effect July 1, 2006, has established a new set of regulations in electronics products. As basic part of electronics, PCBs are defnitely requested to be lead free.

The Price of Lead Free PCB is Affordable

Lead Free PCB have it’s own manfuacturing process.
Lead free hasl pcbs are cheapest compared to Immersion gold pcb, immersion silver pcbs, immersion tin pcbs, except OSP pcbs.

The Advantage of Lead Free PCB Surfacr Finish

However, OSP surface finish has disadvantage of short storage time and get oxidized when open in the air.
Lead FreE hasl finish can be kept more time and is very good for soldering.

Why Choose Lead Free Surface Finish PCB

Lead Free hasl finish are now the most used surface finish on printed circuit production because of following advantages:
excellent wettability, good shelf-file, excellent solder joints, low cost, excellent reflow cycles, excellent surface oxidation and so on.

Not Only:HASL Finish PCB Full Name

HASL Finish PCB Full Name

HASL or Hot Air Solder Leveling is a type of finish used on printed circuit boards (PCB).

How to Manufacturing HASL Finish PCB?

The PCB is typically dipped into a bath of molten solder such that all exposed copper surfaces are covered by solder. Excess solder is removed by scraping the PCB with hot air knives. The HASL process consists of a pre-clean, fluxing, Hot Air Solder Leveling, and a post-clean. Pre-cleaning is usually done with a micro-etch.

How About the Environment of HASL Finish PCB

Despite the effection of RoHS compliance in 2006, normal hasl finish (hot air solder leveling) is still requested nowadays for special products or purpose.

HASL Finish Compare With Lead Free PCB

Hasl finish has excellent wetting during component soldering which is better than lead free hasl finish;
In the other hand,If you project don’t solding small component,HASL Finish PCB also you best choice for you.

HASL Finish PCB Features introduce

Hot Air Solder Leveling on printed circuit board are unsuitable for use with fine pitch components because of low planarity and high thermal stress during process may introduce defects to pcbs.

You shoul know Gold Finger PCB definition

How to introduce gold finger PCB just few steps to your customers?
Jim will discuss gold finger PCB manufacturing in three parts below:

–You shoul know Gold Finger definition
–The use area of Gold Finger
–Introduce of Gold finger PCB

You shoul know Gold Finger definition

Gold Finger is gold-plated terminal of a card-edge connector, usually, fingers are done by flash gold (hard gold) and the gold thickness is requested to be from 3u“ to 50u“ because fingers are mainly used for pluging for many times.
When PCBs will be repeatedly installed and removed electroplated gold is used for edge-connector contacts or as they are more commonly known: Gold fingers.

The use area of Gold Finger

Gold contact surfaces are often used on circuit boards with membrane switches which are a technology of choice for industrial, commercial and consumer products.

Introduce of Gold finger PCB

However, the gold fingers (gold-plated contact pins) found on PCBs are quite unlike Auric’s stubby, fat digits.
To begin with, the plating thickness of a PCB gold finger is typically a mere 300 micro-inch. At this thickness the hard gold is expected to survive 1,000 cycles before wear through.
