Welcome Israel Friends visit us

April 27th, 2018

In the morning of April 24th, 2018, our customer from Israel visited our company. They are very nice and easygoing.

Firstly we had a short meeting in our office to discuss some PCBA projects and component, also we invite them to see our company’s video, which they know more about our capability on PCB, Rigid-flex circuit, FPC, metal core PCB, Ceramic PCB and lead time for different circuit boards.

 

After that, we moved to our SMT plant, where is only 15 minutes far from our office.

In our PCB Assembly plant, we show customers PCBA (SMT) process: First put PCB on Auto-loading machine, then transfer to Auto-Solder-paste-printer, after than go to the next step of components pick & place by SMT machine, after visual checking, board will go throw to reflow oven, QC will check each piece of board after reflowing and then do function testing, or move to AOI process to make sure all components are on the correct position and direction, as well as X-ray testing for the boards with BGA.

 

Each step was monitor and operators are following up with the SOP, to make sure quality is always controlled, and customer are interesting in how we test the assembly boards using testing fixture.

 

 

Customer is very happy with our SMT procedure and become more confident in placing more circuit board and PCBA order with EBest Circuit (Best Technology). After the meeting, we have a quick but delicious Chinese lunch together. And we will visit that customer in the end of May and believe by that time, we can do more things together, as well as good memories with each other.

Appreciate again for their valuable time to visit us, that’s our great pleasure to have that forenoon with them. Look forward seeing them again in Israel in the end of May.

We always welcome customer to visit us, so that they can know about what we can make, not only providing various types of printed circuit board, but also always supporting customer best service with good price.

 

New Automatic Solder paste Printer Adopted in SMT & PCBA

August 25th, 2016

Great news! We (EBest Circuit (Best Technology)) had adopted a new Automatic Solder paste printer for SMT /PCBA since Aug 25th, 2016. We use “G5” which is No. 1 brand in domestic market, made by a Chinese company, the repeated position accuracy is +/-0.01mm, and printing accuracy is +/-0.025mm.

Everybody know the most important element which will affect the quality of SMT /PCBA is the solder past printing quality. Excellent solder paste printing is the base for excellent quality of final SMT /PCBA quality, esp. for the small components such as SMD Chips with small size as 0402, 0201, 01005; IC with small pitch package such QFN, LGA, BGA; Connector with 0.25mm, 0.3mm, 0.40mm pitch.

Here are some pictures of new Automatic Solder paste printer.

Does all kinds of PCB in one panel and combine them together with SMT are available ?

April 22nd, 2016

Yes, we produced all kinds of FR4 PCB in one panel and also combine two kinds FR4 PCB together with SMT so far.

 

Please check the following pictures to know more detail.

  • We put all kinds of boards in one panel to produce, after finish production and separate the boards, you can get several FR4 PCB.

Simple Solderability Test Experiment

August 23rd, 2014

As is well known, solderability is very important for any type of printed circuit boards, we must do solderability test of each batch PCB we made. In this way we can inspect the weldability of the PCB before we go ahead the assembly process, much helpful for SMT.

In our circuit board manufacturing workshop, we have professional equipment to do that testing. But normally these equipment was expensive, and a lot of people want to know a simple and cheap way to do that solderability testing, so today we are doing a simple solderability test and show you all the steps.

1. Take a small solder pot, plug in the power, turn on the switch and heat the solder pot to a certain high temperature(about 8 minutes).

2. Put a tin bar to the solder pot, then you can see the tin bar is begin to melting, slowly into liquid tin, then more and more.

3. After few minutes, there will be enough melting liquid tin in the solder pot to do this test.

4.Use a tweezers to pick up a PCB circuit, first clean the PCB with rubbing alcohol. Because the unclear surface or the oxidation of the PCB will affect the test result.Pick-up-the-PCBclean the PCB
5. This is the key step of this test, put the PCB into the solder pot, depth about 2 mm,time 4-5 seconds is ok. Then you can see the tin will go into the hole of the PCB.

6. Take out the PCB from the solder pot and put it into the cold water. After few seconds, you can see the experimental effect.

This solderability test is very simple and easy. We can see the results very soon. We, EBest Circuit (Best Technology) did solderability of every batch PCB we made, and we also supply our customers with the solderability test report and the test samples.

Any comments about that, leave your message or write email to us. EBest Circuit (Best Technology), always to be your best partner of circuit boards in China!
