BGA inspection

Understanding BGA Assembly Technology

A Ball Grid Array or (BGA) is a SMT (Surface Mount Technology) package that is most commonly used for Integrated Circuits (ICs) with a large number of pins. Ball grid array packaging is a method for reducing package size and integrating a greater number of functions on a single chip module.

With it being a high-density and low-cost packaging option, this technology helps create the best range of circuit boards with precision component placement and soldering excellence.  BGA (Ball Grid Array) also replaces solder balls on the component underside for SMT mounting.  ACME PCB assembly has capabilities that include (ball grid array) BGA assembly and rework up to 65mm squared up to 36-layer printed circuit board.

BGA technology, which uses an array of solder balls for electrical interconnection, offers up several advantages over pin-grid array (PGA).  A couple important advantages of this surface-mount package is:

  • Ball Grid Array enables assemble boards with reduced thickness. This is beneficial when it comes to making sleek electronic products like smart phone, and tablets.
  • They seldom require maintenance and repair.
  • The packaging is more stable because there are no pins that can be bent and broken.
  • Excellent improvement in both thermal and electrical performance, which efficiently uses the space of the circuit board.
  • BGA packaging is compatible with high-efficiency system products.

ACME Printed Circuit Board Assembly started it’s (Ball Grid Array) BGA assembly service in 1994.  With so many years of experience in BGA assembly with X Ray inspection machine, and having the right assembly procedure in place, we are confident in saying that we can build a high quality, good yield rate BGA assembly board.

ACME Printed Circuit Board Assembly is an EMS located in Southern California near Los Angeles airport, it especially for Small to Medium run PCB assembly. Our workmanship meets IPC 610 standard. ISO 9001:2015 certified manufacturer for Electronics Contract manufacturing since Year 2000.

ACME PCB assembly also does BGA prototype assembly for our customers. We are able to create a BGA prototype assembly with or without stencil to help save our customer’s prototyping cost.

What is a PCB Silkscreen on Printed Circuit Boards?

What is a PCB Silkscreen on Printed Circuit Boards?

Were you one of those kids who loved to take apart every electronic thing in your house? If so, you’ve probably pulled out your fair share of green printed circuit boards. It’s cool to hold them and to run your fingers over all their little metallic bumps. When you brought them close to your eye, you could even see little white designs, numbers, and letters drawn on them. What is this mysterious language? It’s called the PCB silkscreen.

The PCB Silkscreen

Silkscreen is the white and human readable letters, normally used to identify components, test points, PCB and PCBA part numbers, warning symbols, company logos, date codes and manufacturer marks.  Silk-screening requires specially formulated inks. The standard color is white, but you can also select red, blue, black, yellow, etc.  Most silkscreens are written in white ink, because it is easy to see against the green solder-mask, but silkscreens can actually be any color. If you take apart enough electronics, you are bound to find PCBs with gray, red, and even blue silkscreens.

Adding the silkscreen layer onto a printed circuit board is the final step in the fabrication process. These shapes, numbers, and letters really aren’t some new language. They act as basically an instruction manual, telling workers how to assemble the board as part of the larger device. They can also communicate the function of each of the pins.  Screen-printing is done when the boards are still penalized prior to the application of the final finish or routing/v-scoring.

PCB layout designers sometimes forget to double-check their silk screen layers before sending designs to PCB fabrication. Designers should avoid putting ident over component pads, they should avoid using excessively tiny text and should allow for registration tolerances.

CNC punching machine

How does Metal Punching Differ from Stamping

Often times, people who are not strictly linked with metal works fields, can confuse between the sheet metal punching and the sheet metal stamping.

This happens because, at first glance, the meaning of these two words might seem the same. On the contrary, the sheet metal punching and the stamping are really different starting from the equipment required to achieve punching and stamping.

The first ones, are metal forming processes realized with automatic CNC machines that use punch presses and dies realizing any kind of hole. The punch pass through the sheet metal while the dies, located on the other side of the metal piece, work as support and help punches to put more force ensuring the non-breaking of metal.

Otherwise, the stamping is the set of operations performed to obtain specific shapes and it includes our sheet metal punching. Stamping is in fact a consequence of others metal processes such as punching, blanking, sheet metal deep-drawing and bending. It’s the ending process useful for giving to metal pieces a specific shape to the entire piece.

To be clear, there’s a third metal process which often is confused and it’s called pressing. The metal pressing, contrary to the sheet metal punching is processed to give shape without breaking the metal piece. For example, pressing process is used to realize corners.

Proud to Be a Lead-Free PCB Assembly Provider

Is lead-free (Pb-Free) also on your mind? It should be. Lead-free (Pb-Free) will impact almost everyone in the electronics industry – from suppliers of component, board and materials like paste and flux to manufacturers and users of electronics products and equipment. Also expect considerable investment both in human resources and capital equipment. Your relationship with your suppliers and customers will also be tested.

There’s a reason that in the United States we no longer allow lead in paint or in gasoline. Though lead is a naturally occurring element, it can be highly toxic to humans. It has been connected with behavior and learning problems, lower IQ, slowed growth, anemia, and even coma and death in severe cases. Children and pregnant women are the most at risk of lead poisoning.

Printed Circuit Board FabricationFor a long time, lead has been part of the soldering process, which is critical to making printed circuit boards. Here at ACME PCB Assembly, we have made the commitment to adopt lead-free solders. Replacing lead solders requires more than just replacing equipment. Lead-free solders have a higher melting point, which means we have had to revise our entire production and assembly process. This required re-training our workers.

Lead-free solder and assembly reliability is achieved if trained specialists carefully implement several process requirements. There are a number of variables that must be taken into consideration to achieve lead-free solder assembly joint reliability.

ACME PCB Assembly is flexible in meeting your requirements. We have offered Lead-Free (Pb-Free) soldering since 2005. Please review Design to Avoid Tin Wiskers for RoHS compliant (Lead-Free) assembly. Though the change was difficult, it was worth it to remove the risk of lead exposure from our facilities.  Now, when you work with us, you know that you are working with a lead-free PCB assembly provider.
