Tools for PCB Designing

Gerber Panelizer

GerberPanelizer is an aide in creating a PCB design. It allows you to edit the layout and then export it as a final merged gerber file. Once exported, the gerber file is locked and cannot be edited or changed. The export will also contain image renderings.

However, it is not a perfect solution. While it is a great tool for panelizing boards, the tool is not very flexible. You need to add fiducials along the board edge and add M4 holes along one side. Nevertheless, the program is extremely easy to use and is an excellent tool for PCB design. It is currently being improved and will be updated in the next version.

Gerber Panelizer is a powerful tool for PCB design. It is very useful for people who build their own PCBs or who are interested in Open Hardware. One major drawback is that it is offered without support and is prone to breaking features. The GUI is window-based and mono.

The main screen of Gerber Panelizer has a list of all the CAM steps. Click on a step to view the contents. You may also click on the step name.

Gerber

When you generate a Gerber file in Altium Designer, you will be able to create multiple board layouts in a single file. Gerber files are files that describe your requirements for PCB fabrication and assembly. They include templates for solder mask, silkscreen pictures, and drill holes. This type of file can be exported to a PCB manufacturer.

You can also insert objects into the panel with the Add Insert command in the right-click menu. To insert an object in the board, you can place it in the parent step or campanel by right-clicking on the board. Make sure to remove the venting pattern that you previously applied. Otherwise, the data will appear without a border.

You can also create a single-sided design and export it as a Gerber. For this, you need to set the top layer of your CAM document to be “top” and then panelize PCB. Then, you can add the Gerbers to the boxes that will be created in the project.

Altium Designer supports the Gerber panelization feature and allows you to create board layouts with multiple designs. With the Gerber panelizer, you can design PCBs with odd shapes and multiple designs on the same panel.

KiKit

Creating panelized printed circuit boards can be a time-consuming process, and the best way to speed it up is by using the KiKit toolkit. It allows you to easily group boards into panels so that they can be reflow soldered together in a quick process. Normally, this requires manually grouping and assembling the boards, but KiKit makes it easy by creating a script that can gang up six boards in a single pass. It uses mousebites to hold them together, so that they can easily be separated after soldering is complete.

KiKit uses a Python-based script to organize the boards into a grid. The script is flexible enough to handle mousebites and v-cuts, and even allows for board separation after production. Since the PCB component distribution is so large, grouping them into panels makes the assembly process much faster. They can then be placed in a reflow oven or pick-and-place machine as one unit.

A panelized PCB needs adequate support to prevent accidental breakout. You can move panels around on the board and adjust edge clearances. Then, you’re ready to build your finished board. Just remember to create a margin of at least one inch on the board. You’ll need to do this for multiple layers.

The panelization process is critical to creating a custom PCB, and Altium Designer provides a host of tools for this task. This includes CAD and CAM features, and the ability to define panelized PCB. Additionally, it integrates design files with panelized PCBs so that it’s easy to make changes without re-making panels.

Nepakankamo lituoklio blizgesio SMT pleistre priežasčių analizė

Insufficient solder gloss on a solder joint is caused by several factors. A component can have inadequate solder, it could have been overheated for a long time, or it could have peeled off at the solder joint due to age or excessive heat.

Cold soldering

The problem of insufficient solder gloss in SMT patches is often caused by inadequate soldering. Insufficient solder gloss can weaken solder joints and increase their susceptibility to failure and cracking. Fortunately, there are ways to remedy the problem, including applying more solder or reheating the joints.

Insufficient solder gloss is caused by either insufficient flux or too much heat during soldering. Insufficient wetting can also result from a failure to evenly heat both the pin and the pad or a lack of time for solder to flow. When this happens, a layer of metal oxide can form on the bonded object. In such cases, a repair technique should be used to clean the board and apply the solder evenly to the two components.

PCB oxidation

Insufficient solder gloss at SMT patch may be caused by a number of reasons. One common problem is improper solder paste storage and operation. The solder paste may be too dry or have an expired date. The solder paste may also have a poor viscosity. In addition, the solder paste can become contaminated with tin powder during the patch.

Typically, this problem occurs when PCBs are left unprotected for a long time. Another common cause of poor solder joints is oxidation of the surface mount pad. Oxidation can occur on the surface of the PCB during storage or during shipping. Regardless of the cause of the issue, it is important to take steps to prevent this from happening.

Solder balls

Solder balls are tiny balls of solder which can have serious consequences for the functionality of a circuit board. Small balls can move components off-mark and larger balls can degrade the solder joint quality. Also, they can roll on to other parts of the board, causing shorts and burns. These problems can be avoided by ensuring that the PCB base material is dry before reflowing.

Choosing the proper solder paste to use during soldering is a key element in minimizing the risk of solder balls. Using the right paste can greatly reduce the chances of having to rework a board. A slow preheat rate will allow the solder to spread evenly throughout the surface and prevent the formation of solder balls.

Excess solder

Excess solder gloss in SMT patch processes is often caused by a combination of factors. The first is a low preheating temperature, which will affect the appearance of the solder joint. The second is the presence of solder residue. The latter can make the solder joint appear dull or even numb.

Soldering paste smearing on the stencil is another common cause. If the paste has not reflowed properly, the excess solder can flow and obscure the solder joint connection. To remove excess solder, use a solder sucker, a solder wick, or a hot iron tip.

Miswelding

Solder joints with insufficient gloss can be a result of miswelding. The solder may have poor wetting, be dark or non-reflective, or be too rough to look good. The underlying cause is that the solder was not heated sufficiently to reach a high enough temperature for the solder to melt completely.

Solder paste fails to do its soldering job because it is not properly mixed or stored. The paste may not be completely re-dissolved in the solder bath, and the tin powder may spill out during the soldering process. Another cause is that the solder paste may have an expired date. A seventh possible cause of insufficient solder gloss at an SMT patch is a result of the production technology used by the solder paste supplier.

Solder voids

Solder voids in SMT patches can negatively impact a component’s reliability and functionality. They reduce the solder ball’s cross-section, which reduces the amount of solder that can transfer heat and current. Also, during reflow, small pre-existing voids can merge to form large voids. Ideally, voids should be eliminated or reduced to a manageable level. However, many studies indicate that moderate voids can increase reliability by reducing crack propagation and increasing the solder joint’s height.

Solder voids in SMT patches are not a serious problem if they are infrequently occurring and do not affect reliability. However, their presence in a product signals a need for adjustment in manufacturing parameters. Some factors may contribute to the presence of solder voids in SMT patches, including trapped flux and contaminants on circuit boards. The presence of these voids can be visually detected in X-ray images, where they appear as a lighter spot inside the solder ball.

4 žingsniai, kaip pagaminti tobulą aliuminio PCB

Norint pagaminti tobulą aliuminio PCB, reikia atlikti keletą veiksmų. Pirmasis žingsnis - nuspręsti, kiek sluoksnių ir sluoksnių turi būti spausdintinėje plokštėje. Tada turite pasirinkti medžiagas, kurios bus naudojamos skirtingose PCB dalyse. Po to reikia nuspręsti, ar aliuminį norite patalpinti į šerdies sluoksnį, ar jis bus sujungtas su aplinkiniais dielektriko sluoksniais skiriamąja membrana. Kitas variantas - iš galinės pusės montuojama plokštelė arba net išpjovos.

Tobulos aliuminio spausdintinės plokštės gamybos procesai

Aliuminio PCB yra įprasta medžiaga, naudojama daugelyje programų. Didžiausi naudotojai yra elektros energijos tiekimo įmonės, LED keitikliai ir radijo dažnių įmonės. Dauguma aliuminio PCB yra gaminami kaip vienas sluoksnis. Taip yra todėl, kad vienas aliuminio sluoksnis sudaro didelę plokštės šiluminės struktūros dalį. Gamybos proceso metu aliuminio pagrindo sluoksnyje išgręžiamos skylės ir užpildomos dielektrine medžiaga.

Dėl aliuminio PCB savybių jis yra puiki elektroninės įrangos medžiaga. Jis pasižymi dideliu laidumu ir mažu plėtimosi koeficientu. Dėl šių savybių jis idealiai tinka didelės galios įrenginiams. Aliuminio spausdintinės plokštės taip pat tinka naudoti aukštatemperatūrėse grandinėse.

Norint pagaminti aliuminio PCB, reikia parengti plokštės dizainą. Baigus kurti dizainą, gamintojas pradės gamybos procesą. Tada aliuminio šerdis padengiama skiriamuoju sluoksniu, o PCB laminatai klijuojami ant aliuminio laikančiosios plokštės. Šio etapo metu išgręžiamos skylės, kad būtų sukurta pakankamai didelė erdvė komponentams sutalpinti. Tuomet šios skylės padengiamos lydmetaliu ir uždaromos lydmetalio kauke.

Naudotos medžiagos

Aliuminis yra metalas, pasižymintis dideliu atsparumu karščiui ir naudojamas spausdintinėms plokštėms gaminti. Šilumos laidumas rodo, kiek šilumos gali būti perduota per ploto vienetą per vieną kilovatvalandę (kW/m.h.). Kuo didesnis medžiagos šiluminis laidumas, tuo ji geriau izoliuoja ir išsklaido šilumą. Aliuminio nugarėlės spausdintinės plokštės idealiai tinka tais atvejais, kai reikalingas didelis šilumos išsklaidymas.

Aliuminio PCB gamintojai šio tipo plokštėms gaminti naudoja įvairius metodus. Jie gali išgręžti plokštę ir joje padaryti keletą mažų skylučių. Šios skylutės naudojamos grandinės komponentams, pavyzdžiui, jungikliams ir mikroschemoms, montuoti. Kad jie tinkamai veiktų, juos reikia prijungti prie spausdintinės plokštės. Aliuminio plokštė taip pat padengta izoliacinėmis medžiagomis, todėl ji nėra laidi.

Aliuminio PCB yra labiausiai paplitęs tipas. Jų aliuminio šerdį supa vario folija. Ši medžiaga puikiai išsklaido šilumą ir puikiai tinka programoms, kurioms reikia daugiau galios. Aliuminio spausdintinės plokštės pirmą kartą buvo sukurtos praėjusio amžiaus aštuntajame dešimtmetyje ir šiuo metu naudojamos maitinimo sistemose, LED apšvietime ir automobilių sistemose. Aliuminio PCB ne tik atsparios karščiui, bet ir gali būti perdirbamos.

Lituoklio kaukės spausdinimas

Naudojamos lydmetalio kaukės tipą lemia keli veiksniai, įskaitant plokštės dydį ir išdėstymą, komponentų ir laidininkų tipą bei numatomą galutinį pritaikymą. Be to, reguliuojamose pramonės šakose taikomi specialūs reikalavimai. Šiuo metu dažniausiai naudojamos skystos fotografinio atvaizdavimo litavimo kaukės, kurios yra labai patikimos. Jos taip pat žinomos kaip mažinančios PCB atspindžius.

Naudojant litavimo kaukes, reljefo sritis tarp litavimo pastos ir spausdintinės plokštės turi būti tiksliai išdėstyta, kad lydmetalis tinkamai priliptų. Jei lydmetalio kaukė neuždengia viso spausdintinės plokštės paviršiaus, gali įvykti trumpasis jungimas. Be to, lydmetalio kaukėse gali būti bandomųjų taškų ir perėjimų.

Lituoklio kaukės naudojamos plokštėje esančioms angoms pažymėti, tada ant jų galima lituoti komponentų kaiščius. Kai kuriais atvejais lituoklio kaukės atspausdinamos ant plokštės epoksidiniu arba plėveliniu būdu. Lituoklio pasta ant plokštės užtepama naudojant šias angas, kad komponentai būtų patikimai sujungti elektriniu ryšiu. Viršutinės pusės kaukė naudojama viršutinei plokštės pusei, o apatinės pusės kaukė - apatinei plokštės pusei.

Aukšto slėgio bandymas

Gaminant aliuminio PCB, būtina užtikrinti, kad izoliacinis sluoksnis būtų be įtrūkimų ar įbrėžimų. Be to, valdymo padėtis ir kontūro tolerancija turi atitikti projekto reikalavimus. Taip pat svarbu pašalinti bet kokius metalo trupinius, kurie gali turėti įtakos plokštės elektriniam pajėgumui. Siekiant atitikti šiuos reikalavimus, turi būti atliktas aukšto slėgio bandymas. Plokštės veikiamos ****KV nuolatinės srovės slėgiu, o šliaužimo srovė nustatoma **mA/PCS. Atlikdami bandymus bandytojai turi mūvėti izoliuotas pirštines ir avėti batus, kad apsisaugotų nuo aukšto slėgio aplinkos. Be to, OSP plėvelė turi būti nurodytos apimties.

Automatinio bandymo atlikimas yra labai svarbus gamybos procesui. Šis metodas yra tikslesnis ir greitesnis nei rankinis tikrinimas, be to, juo galima nustatyti tendencijas, dėl kurių galima tobulinti procesą. Šį testą išlaikiusios spausdintinės plokštės perkeliamos į galutinius spausdintinių plokščių gamybos etapus.
